    Abstract: SQL*Plus is available at every Oracle site--from the largest data warehouse to the smallest single-user system--and it's a critical tool for virtually every Oracle user. Despite its wide use, few developers and DBAs know how powerful a tool SQL*Plus can be. This pocket reference provides quick reference information that will help you use SQL*Plus, Oracle's interactive query tool. It summarizes all of the SQL*Plus syntax, including the syntax for the Oracle9i release. This book boils down the most vital information from Gennick's best-selling book, "Oracle SQL8Plus: The Definitive Guide", into an accessible summary and works as a vital companion to the larger book. It concisely describes interacting with SQL*Plus, selecting data, formatting reports with SQL*Plus, and tuning SQL queries. It also contains quick references to the SQL*Plus commands and format elements. The new 2nd edition of our Oracle SQL*Plus Pocket Reference includes many new features for Oracle9i (e.g., COALESCE function, searched CASE expressions, new table join syntax, partition operations, MERGE statement, and syntax changes in existing SQL*Plus statements such as ACCEPT, DESRIBE, HELP, and SET) It also adds sections on basic SQL (a much-requested feature): INSERT, DELETE, UPDATE, SELECT, and transaction management. The pocket reference size is especially appropriate for this particular subject, since Oracle SQL*Plus is used on every possible platform, it's particularly convenient to be able to carry a small book around from office computer to home computer to laptop.

    Abstract: The web services architecture provides a new way to think about and implement application-to-application integration and interoperability that makes the development platform irrelevant. Two applications, regardless of operating system, programming language, or any other technical implementation detail, communicate using XML messages over open Internet protocols such as HTTP or SMTP. The Simple Open Access Protocol (SOAP) is a specification that details how to encode that information and has become the messaging protocol of choice for Web services. Programming Web Services with SOAP is a detailed guide to using SOAP and other leading web services standards--WSDL (Web Service Description Language), and UDDI (Universal Description, Discovery, and Integration protocol). You'll learn the concepts of the web services architecture and get practical advice on building and deploying web services in the enterprise. This authoritative book decodes the standards, explaining the concepts and implementation in a clear, concise style. You'll also learn about the major toolkits for building and deploying web services. Examples in Java, Perl, C#, and Visual Basic illustrate the principles. Significant applications developed using Java and Perl on the Apache Tomcat web platform address real issues such as security, debugging, and interoperability. Covered topic areas include: The Web Services Architecture SOAP envelopes, headers, and encodings WSDL and UDDI Writing web services with Apache SOAP and Java Writing web services with Perl's SOAP::Lite Peer-to-peer (P2P) web services Enterprise issues such as authentication, security, and identity Up-and-coming standards projects for web services Programming Web Services with SOAP provides you with all the information on the standards, protocols, and toolkits you'll need to integrate information services with SOAP. You'll find a solid core of information that will help you develop individual Web services or discover new ways to integrate core business processes across an enterprise.

    Abstract: JDBC is the key Java technology for relational database access. Oracle is arguably the most widely used relational database platform in the world. In this book, Donald Bales brings these two technologies together, and shows you how to leverage the full power of Oracle's implementation of JDBC. You begin by learning the all-important mysteries of establishing database connections. This can be one of the most frustrating areas for programmers new to JDBC, and Donald covers it well with detailed information and examples showing how to make database connections from applications, applets, Servlets, and even from Java programs running within the database itself. Next comes thorough coverage of JDBC's relational SQL features. You'll learn how to issue SQL statements and get results back from the database, how to read and write data from large, streaming data types such as BLOBs, CLOBs, and BFILEs, and you'll learn how to interface with Oracle's other built-in programming language, PL/SQL. If you're taking advantage of the Oracle's relatively new ability to create object tables and column objects based on user-defined datatypes, you'll be pleased with Don's thorough treatment of this subject. Don shows you how to use JPublisher and JDBC to work seamlessly with Oracle database objects from within Java programs. You'll also learn how to access nested tables and arrays using JDBC. Donald concludes the book with a discussion of transaction management, locking, concurrency, and performance--topics that every professional JDBC programmer must be familiar with. If you write Java programs to run against an Oracle database, this book is a must-have.

    Abstract: Executable UML is a major innovation in the field of software development. It is designed to produce a comprehensive and understandable model of a solution independent of the organization of the software implementation. It is a highly abstract thinking tool that aids in the formalization of knowledge, and is also a way of describing the concepts that make up abstract solutions to software development problems. This timely new book, Executable UML: A Foundation for Model-Driven Architecture, thoroughly introduces, documents, and explains this important new technology. The authors show how UML can formalize requirements and use cases into a rich set of verifiable diagrams, how it can be used to produce executable and testable models, and how these models can be translated directly into code. In addition, the book explains how individual system domains are woven together by an executable UML model compiler. The book is full of tips and techniques to help you: Partition a system into subject matters based on individual aspects Pick the right level for use case modeling to speed subject matter comprehension Model classes and focus on relationships to capture subject matter semantics precisely Express behavior using the newly adopted UML action semantics and action languages Specify constraints using tags specified in OCL (Object Constraint Language) In addition, this book tackles topics of particular importance in execution, such as how to: Synchronize objects by building lifecycles using statechart diagrams Model relationships and contention safely Distribute dynamics to avoid unmaintainable controller objects Verify the models by executing test cases against the statechart diagrams and constraints A large-scale, fully developed case study runs throughout the book to illustrate concepts and techniques. These models, plus tools to translate and run Executable UML models, can be downloaded from the book's websites, www.executableumlbook.com and www.projtech.com. 0201748045B05092002

    Abstract: Java Data Objects is a standardized Java API for object persistence. It facilitates the storage and retrieval of complex object models with various storage mechanisms, including both object and relational databases. Analysts agree that JDO's transparent persistence will accelerate software development and yield more flexible applications and object models. According to Infoworld , "The JDO standard promises to be a winner for business leaders and corporate developers alike. Unifying data access--that is, using familiar Java constructs to access information housed in relational databases, object databases, file systems, or even flash RAM--means that corporate applications will experience an increase in usability, portability and integration". This book is for Java developers, designers and architects with a good understanding of the Java language who wish to write applications that use JDO for persistence. Prior knowledge of JDBC and J2EE is not specifically required, but would help to accelerate the reader's understanding of JDO's relationship with these technologies. The companion CD-ROM includes the following JDO implementations:FastObjects, Kodo JDO, LiDO and OpenFusion JDO. 0321123808B08192002

    Abstract: Malicious mobile code is a new term to describe all sorts of destructive programs: viruses, worms, Trojans, and rogue Internet content. Until fairly recently, experts worried mostly about computer viruses that spread only through executable files, not data files, and certainly not through email exchange. The Melissa virus and the Love Bug proved the experts wrong, attacking Windows computers when recipients did nothing more than open an email. Today, writing programs is easier than ever, and so is writing malicious code. The idea that someone could write malicious code and spread it to 60 million computers in a matter of hours is no longer a fantasy. The good news is that there are effective ways to thwart Windows malicious code attacks, and author Roger Grimes maps them out in Malicious Mobile Code: Virus Protection for Windows. His opening chapter on the history of malicious code and the multi-million dollar anti-virus industry sets the stage for a comprehensive rundown on today's viruses and the nuts and bolts of protecting a system from them. He ranges through the best ways to configure Windows for maximum protection, what a DOS virus can and can't do, what today's biggest threats are, and other important and frequently surprising information. For example, how many people know that joining a chat discussion can turn one's entire computer system into an open book? Malicious Mobile Code delivers the strategies, tips, and tricks to secure a system against attack. It covers: The current state of the malicious code writing and cracker community How malicious code works, what types there are, and what it can and cannot do Common anti-virus defenses, including anti-virus software How malicious code affects the various Windows operating systems, and how to recognize, remove, and prevent it Macro viruses affecting MS Word, MS Excel, and VBScript Java applets and ActiveX controls Enterprise-wide malicious code protection Hoaxes The future of malicious mobile code and how to combat such code These days, when it comes to protecting both home computers and company networks against malicious code, the stakes are higher than ever. Malicious Mobile Code is the essential guide for securing a system from catastrophic loss.

    Abstract: In this book, Steven Feuerstein, widely recognized as one of the world's experts on the Oracle PL/SQL language, distills his many years of programming, writing, and teaching about PL/SQL into a set of PL/SQL language "best practices"--rules for writing code that is readable, maintainable, and efficient. Too often, developers focus on simply writing programs that run without errors--and ignore the impact of poorly written code upon both system performance and their ability (and their colleagues' ability) to maintain that code over time. Oracle PL/SQL Best Practices is a concise, easy-to-use reference to Feuerstein's recommendations for excellent PL/SQL coding. It answers the kinds of questions PL/SQL developers most frequently ask about their code: How should I format my code? What naming conventions, if any, should I use? How can I write my packages so they can be more easily maintained? What is the most efficient way to query information from the database? How can I get all the developers on my team to handle errors the same way? The book contains 120 best practices, divided by topic area. It's full of advice on the program development process, coding style, writing SQL in PL/SQL, data structures, control structures, exception handling, program and package construction, and built-in packages. It also contains a handy, pull-out quick reference card. As a helpful supplement to the text, code examples demonstrating each of the best practices are available on the O'Reilly web site. Oracle PL/SQL Best Practices is intended as a companion to O'Reilly's larger Oracle PL/SQL books. It's a compact, readable reference that you'll turn to again and again--a book that no serious developer can afford to be without.

    Abstract: Net8 is the fundamental Oracle technology that allows Oracle services and clients to communicate with each other over a network. Net8 is most often used to connect client software to Oracle database servers. It may also be used to connect database servers to one another, allowing communication between distributed databases. This practical guide provides the information that readers, especially database administrators, need to know in order to install configure, tune, and troubleshoot Net8. It discusses how Oracle's network architecture, products, and name resolution methods work, and it provides the details of client and server configuration using a variety of Oracle protocols and networking products, including: The Oracle Internet Directory (OID), Oracle's implementation of the standard Lightweight Directory Access Protocol (LDAP). This directory can be used to maintain a central repository of net service names that can be referenced by all clients. Oracle Names, a networking component used mainly in earlier versions of Oracle, that allows net service names to be defined centrally. Multi-Threaded Server (MTS), an environment in which the client connections share access to a pool of shared server processes. Oracle Connection Manager, a Net8 component that acts much like a router and provides protocol conversion, connection concentration, and access control. The book also describes the utilities Oracle provides to help manage a Net8 environment; these include the Listener Control Utility (lsnrctl), the Oracle Names Control Utility (namesctl), the Oracle Connection Manager Control Utility (cmctl), tnsping, and Net8 Assistant. In addition, it provides a variety of networking troubleshooting techniques and commonly encountered Net8 configuration problems, and provides complete syntax for all networking files and commands.

    Abstract: REALbasic is a programming language in the best Macintosh tradition: visual, intuitive, and easy to learn. It allows you to create interfaces in minutes and entire, compiled applications without having to learn a complicated language; the strong object orientation makes it very easy even for beginners to develop, maintain, and alter projects. Best of all, an REALbasic 3, a single button click generates your project as a Mac OS 8/9 application, a Mac OS X native ("Carbon") application, or a Windows executable. No other application framework lets you compile for users on so many platforms so quickly and easily. REALbasic: The Definitive Guide not only gives you a firm grasp of the program's essential concepts, but also tells you things you won't learn from the official documentation alone. If you've never programmed before, the book offers both a primer in REALbasic and an intuitive approach to the concepts of programming itself, as you quickly reach the ability to program every aspect of REALbasic. You start out drawing the interface much as you would do in a drawing program: by selecting buttons, menus, dialog boxes, and the like from a tools menu. Then you use the code editor to fill in the code that tells these pieces what to do.The widely hailed first edition of REALbasic: The Definitive Guide has been completely rewritten to encompass reader suggestions and the many improvements of REALbasic 3--like its ability to compile and run under OS X.The book is divided into three sections: Fundamentals: a detailed summary of the language that quickly shows you how to think about programming and accomplish your goals in less time User Interface: how to create a complete application using the rich classes and pre-defined tools that make life so much easier for the REALbasic programmer. Reaching Out: Internet communications, databases, multimedia, game programming and more!

    Abstract: If you're a Java programmer working in an Oracle environment, you're probably familiar with JDBC as a means of accessing data within an Oracle database. SQLJ takes you further, allowing you to access a database using embedded SQL statements. Java Programming with Oracle SQLJ shows you how to get the most out of SQLJ. Layered on top of JDBC, SQLJ greatly simplifies database programming. Rather than make several calls to the JDBC API just to execute a simple SQL statement, SQLJ executes that statement simply by embedding it within the Java code. In this book, Jason Price explains SQLJ programming from a task-oriented point of view. You'll learn how to: Embed queries and other SQL statements within Java programs Deploy SQLJ code not only on client machines, but also to JServer--Oracle's Java engine built into the database Use advanced techniques for working with collections, streams, large objects, and database objects, all without leaving the comfort of the SQLJ environment Tune SQLJ programs for maximum performance Throughout the book, the exposition of SQLJ and SQLJ programming techniques reflects the author's many years of professional experience as a programmer and consultant. Examples are first-rate, enabling you to learn SQLJ in no time. If you're writing Java code to access an Oracle database, you can't afford not to know about SQLJ.

    Abstract: SQL Loader is a ubiquitous tool in the Oracle world. It has been shipped with Oracle since at least Version 6 and continues to be supported and enhanced with each new version of Oracle, including Oracle8 and Oracle8 i. The job of SQL Loader is to load data from flat files into an Oracle database. It's optimized for loading large volumes of data, and is flexible enough to handle virtually any input format.Almost every Oracle user has to use SQL Loader at one time or another, and DBAs are frequently called upon to load data for the users in their organization. Despite SQL Loader's wide availability and usage, few DBAs and developers know how to get the most out of it. Oracle SQL Loader: The Definitive Guide has everything you need to know to put SQLLoader to its best use: an introduction to SQL Loader, a reference to all of its syntax options, and most importantly, step-by-step instructions for all the SQL Loader tasks you'd want to perform--and maybe some you didn't realize you COULD perform.You'll learn how to construct the necessary control files and load from different types of files containing different types of data (e.g., fixed-width data, delimited data, and data of various datatypes). You'll also learn how to validate data, load it selectively, transform it as it is loaded, and recover after failure. This book explains how to optimize SQL Loader performance by adjusting the transaction size and using the new direct path option. It also covers the newest SQL Loader features--the loading of large object (LOB) columns and the new object types (nested tables, varying arrays, and object tables). Oracle SQL Loader: The Definitive Guide is an indispensable resource for anyone who is new to SQLLoader; a task-oriented learning tool for those who are already using it; and a quick reference for every user. If you want to take best advantage of an essential Oracle tool, you need this book.

    Abstract: One of Java's most striking claims is that it provides a secure programming environment. Yet despite endless discussion, few people understand precisely what Java's claims mean and how it backs up those claims. If you're a developer, network administrator or anyone else who must understand or work with Java's security mechanisms, Java Security is the in-depth exploration you need. Java Security, 2nd Edition, focuses on the basic platform features of Java that provide security--the class loader, the bytecode verifier, and the security manager--and recent additions to Java that enhance this security model: digital signatures, security providers, and the access controller. The book covers the security model of Java 2, Version 1.3, which is significantly different from that of Java 1.1. It has extensive coverage of the two new important security APIs: JAAS (Java Authentication and Authorization Service) and JSSE (Java Secure Sockets Extension). Java Security, 2nd Edition, will give you a clear understanding of the architecture of Java's security model and how to use that model in both programming and administration.The book is intended primarily for programmers who want to write secure Java applications. However, it is also an excellent resource for system and network administrators who are interested in Java security, particularly those who are interested in assessing the risk of using Java and need to understand how the security model works in order to assess whether or not Java meets their security needs.

    Abstract: Oracle & Open Source is the first book to tie together the commercial world of Oracle and the free-wheeling world of open source software. As this book reveals, these two worlds are not as far apart as they may seem. Today, there are many excellent and freely available software tools that Oracle developers and database administrators can use, at no cost, to improve their own coding productivity and their system's performance. Moreover, many of the finest Oracle developers are now making their source code freely available so their peers can build upon this code base. Oracle Corporation is even porting its RDBMS to Linux and starting to incorporate a growing number of open source tools in the company's own software. Oracle & Open Source describes close to 100 open source tools you can use for Oracle development and database administration, from large and widely known open source systems (like Linux, Perl, Apache, TCL/Tk and Python) to more Oracle-specific tools (like Orasoft, Orac, OracleTool, and OraSnap). You'll learn how to obtain the software and how to adapt it to best advantage. The book abounds with code examples, download and installation instructions, and helpful usage hints. Not only does it tell you how to find and use existing open source code; Oracle & Open Source gives you the details and the motivation to build your own open source contributions and release them to the Oracle community. You'll learn all about tools like the Oracle Call Interface (OCI) and Perl-DBI (Database Interface), which provide the glue allowing new open source tools to link into commercial Oracle software. With Oracle & Open Source as a guide, you'll discover an enormous number of highly effective open source tools, while getting involved with the thriving community of open source development.

    Abstract: A Practical Guide to Testing Object-Oriented Software focuses on the real-world issues that arise in planning and implementing effective testing for object-oriented and component-based software development. It shows how testing object-oriented software differs from testing procedural software and highlights the unique challenges and opportunities inherent in object-oriented software testing. The authors reveal how object-oriented software development allows testing to be integrated into each stage of the process--from defining requirements to system integration--resulting in a smoother development process and a higher end quality. As they follow this process, they describe what to test at each stage as well as offer experienced-based testing techniques. You will find information on such important topics as: Testing analysis and design models, including selecting test cases to guide design inspections Testing components, frameworks, and product lines The testing challenges of inheritance and polymorphism How to devise an effective testing strategy Testing classes, including constructing a test driver and test suites Testing object interactions, covering sampling test cases, off-the-shelf components, protocol testing, and test patterns Testing class hierarchies, featuring subclass test requirements Testing distributed objects, including threads, life cycle testing, and Web server testing Testing systems, with information on stress, life cycle, and performance testing One comprehensive example runs throughout the book to demonstrate testing techniques for each stage of development. In addition, the book highlights important questions that testers should ask when faced with specific testing tasks. The authors acknowledge that testing is often viewed as a necessary evil, and that resources allocated to testing are often limited. With that in mind, they present a valuable repertoire of testing techniques from which you can choose those that fit your budget, schedule, and needs. 0201325640B04062001

    Abstract: With COM and .NET Component Services, skilled COM developers can leverage their knowledge for the next generation of components to be built for Microsoft's new .NET framework. A primary goal of Microsoft's COM+ is to provide proven design solutions for scalable systems. Assuming experience with classic COM, COM and .NET Component Services focuses on the added services of COM+, including support for transactions, queued components, events, concurrency management, and security. Along the way, it ably demonstrates that COM+ is a masterpiece of design and usability from the ground up--truly a mature set of component services oriented for the middle tier. COM+ provides a foundation for robust, enterprise-wide, mission-critical distributed applications. And it's not limited to Internet applications. You can use COM+ services in the same places as classic COM components: in-house two-tier information systems, client-tier controls, desktop applications, machine control components, and every other conceivable application of COM. COM and .NET Component Services is the first book to stress the importance of learning to use COM+ services for both .NET and COM component-based applications. Since most companies have considerable investment in existing code base and development skills, COM+ can serve as a migration path for companies and developers. Companies can start (or continue) their projects in COM, using COM+ as a supporting platform for component services, and then when the time comes to move to .NET, they can start plugging .NET components seamlessly into the same architecture, reusing and interacting with their existing COM components.

    Abstract: Cocoa™ is one of the principal application environments for Mac® OS X. Among Cocoa's many attributes, its advanced object-oriented APIs allow you to develop in both Java and Objective-C. This revolutionary new way of developing sophisticated applications for the Macintosh is both powerful and easy. With Learning Cocoa you'll become familiar with Cocoa application development, using Objective C, not merely by reading, but by doing. The book begins with a discussion of essential object-oriented programming concepts for those with no previous experience. It proceeds through an introduction to the Cocoa environment, development, tools, and some simple tutorials to help you become familiar with the basic elements of Cocoa programming. The remaining tutorials guide you as you create a series of increasingly complex example applications. The techniques and concepts you learn in one tutorial lay the foundation for the more advanced techniques and concepts in the next. You don't need extensive programming experience to complete the examples in this book, though it would be helpful to have some experience with the C programming language. The code for each example is included in the text so you can simply type it in. If you're already familiar with an object-oriented programming language like Java or Smalltalk, you'll quickly feel right at home with Objective-C, the language used throughout this book. As you ease your way into the experience of Cocoa programming, you're encouraged to play, to explore, to "kick the tires." You'll finish this book much better prepared to take on serious application development with Cocoa, and you'll find Apple's development environment not only less mysterious, but one that you'll be eager to program in. Written by insiders at Apple Computer, the book brings you information that you can't get anywhere else--and a potential leg up in the Mac OS X application development market.

    Abstract: SQL (Structured Query Language) is the heart of a relational database management system. It's the language used to query the database, to create new tables in the database, to update and delete database fields, and to set privileges in the database. Oracle SQL: The Essential Reference is for everyone who needs to access an Oracle database using SQL--developers, DBAs, designers, and managers. SQL is based on research dating back to the late 1960s, but its first commercial release was in the RDBMS announced by the fledgling Oracle Corporation in 1979. Since that time, every other database vendor has adopted SQL, and ANSI and the ISO have made it a standard. Although vendors diverge in their extensions to SQL, the core language is standard across vendor boundaries. Despite SQL's long history and relative simplicity, few developers and database administrators are truly masters of SQL. The constant stream of vendor enhancements, the hard-won experience in tuning SQL for best performance, and the requirements of particular operational environments mean that there is always more to learn about SQL. Oracle SQL: The Essential Reference delivers all the information needed to keep ahead of the learning curve on standard SQL and Oracle's extensions to it. This single, concise reference volume will hold its own against a stack of Oracle manuals and even yield insights and examples not available in those manuals. There are chapters on basic SQL elements (naming requirements, column types, pseudo-types, data conversion rules, operators); Data Definition Language (DDL) and Data Manipulation Language (DML); common language elements (constraints, storage clause, predicates); SQL functions; PL/SQL (including procedures, functions, and packages); SQL*Plus, and Oracle SQL optimization and tuning. The book covers Oracle 8 i, release 8.1.6.

    Abstract: Oracle Developer Forms Techniques describes the concepts and techniques needed to build Web-enabled applications with Forms. The book covers advanced topics in great detail, including understanding and overcoming error handling limitations in Forms, such as errors which cannot be tracked through normal FORM_SUCCESS or FORM_FAILURE, ordering by items based on FK look-ups, obtaining Query Count without actually executing a query, and performing an exclusive server-side commit from Forms. The book also covers object-oriented methods in Forms, and Intelligence in Forms. Code segments are provided to help developers implement these techniques, thus easing application development time and effort.

    Abstract: If you write programs to run against an Oracle database, you spend a lot of time and mental energy writing queries to return the data your programs need. Knowledge of SQL, and particularly of Oracle's implementation of SQL, is the key to writing good queries in a timely manner. In this book, the authors share their knowledge of Oracle SQL, and show you many creative techniques that you can use to advantage in your own applications. This book shows you how to: Leverage Oracle's vast library of built-in SQL functions Query time-based data, and write joins involving date and time ranges Use Oracle SQL's hierarchical query features to deal with data best represented in a tree format Use DECODE and CASE to implement conditional logic in your queries Use Oracle's new, analytic SQL features to write ranking queries, lag and lead queries, windowing queries, and more Join data from two or more tables using the newly supported SQL92 join syntax In addition, you'll see how SQL can best be integrated with PL/SQL. You'll also learn various best practices to help you write SQL queries that perform efficiently. Precious few books on the market today go beyond discussing syntax and the barest rudiments of using Oracle SQL. This book changes that, showing you how to creatively leverage the full power of SQL to write queries in an Oracle environment.

    Abstract: This pocket reference provides quick reference information that will help you use SQL*Plus, Oracle's interactive query tool. It summarizes all of the SQL*Plus syntax, including the syntax for new Oracle8 i release 8.1.6 features. SQL*Plus is available at every Oracle site--from the largest data warehouse to the smallest single-user system--and it's a critical tool for virtually every Oracle user. Despite its wide use, few developers and DBAs know how powerful a tool SQL*Plus can be. This book boils down the most vital information from Gennick's best-selling book, Oracle SQL*Plus: The Definitive Guide , into an accessible summary. It concisely describes interacting with SQL*Plus, selecting data, formatting reports with SQL*Plus, and tuning SQL queries. It also contains quick references to the SQL*Plus commands and format elements. This book is an indispensable companion to O'Reilly bestselling book, Oracle SQL*Plus: The Definitive Guide , but it does not replace it; the larger book is truly the definitive guide, suitable for readers at all levels of expertise. The definitive guide describes the many tasks that SQL*Plus can perform, and provides a tutorial on many SQL*Plus topics. But this quick reference is an excellent, portable resource for readers who want a pocket-sized summary of SQL*Plus capabilities and a reminder of how to issue specific commands and formatting options for SQL*Plus.

    Abstract: Parallel processing is becoming increasingly important to database computing. Databases often grow to enormous sizes and are accessed by huge numbers of users. This growth strains the ability of single-processor and single-computer systems to handle the load. More and more, organizations are turning to parallel processing technologies to give them the performance, scalability, and reliability they need. Anyone managing a large database, a database with a large number of concurrent users, or a database with high availability requirements--such as a heavily trafficked e-commerce site--needs to know how to get the most out of Oracle's parallel processing technologies. Oracle Parallel Processing is the first book to describe the full range of parallel processing capabilities in the Oracle environment, including those new to Oracle8 i. It covers: What is parallel processing--features, benefits, and pitfalls. Who needs it and who doesn't? What features does Oracle provide, and what are their requirements and overhead implications? The book answers these questions and presents the various parallel architectures (SMP, or Symmetric Multiprocessing; MPP, or Massively Parallel Processing; clustered systems; and NUMA, or Non Uniform Memory Access). Oracle parallel execution--Oracle supports a variety of parallel execution features in the database. The book covers the use, administration, and tuning of these features: parallel query, parallel data loading, parallel DML (Data Manipulation Language), parallel object creation (through DDL, or Data Definition Language), and parallel replication propagation. Oracle Parallel Server--Oracle also provides the OPS option, which work to be spread over both multiple CPUs and multiple nodes. This book covers OPS architecture, requirements, administration, tuning, storage management, recovery, and application failover issues. Oracle Parallel Processing also contains several case studies showing how to use Oracle's parallel features in a variety of real-world situations.

    Abstract: Computers and devices are more connected now than ever before. Why? Because the humans who use those computers need to collaborate. We need to share information, and we need to do it quickly, without regard to the physical distance that separates us. Corporate solution developers now more than ever have the opportunity and responsibility to enable people to communicate in ways never before possible. CDO and MAPI Programming with Visual Basic: Developing Mail and Messaging Applications dives deep into Microsoft's Collaboration Data Objects (CDO) and the Messaging Application Programming Interface (MAPI), then moves into succinct explanations of the types of useful messaging applications that can be written in Visual Basic. Microsoft has given the Visual Basic community Collaboration Data Objects (CDO)--a technology that goes far beyond simple email, fully into the realm of information workflow. CDO enables Visual Basic applications to exchange not only classic email, but in fact any information in a straightforward and easy way. The Internet--sometimes seen as a barrier by developers--is turned into an open pipe, ready to take your application's data around the world. Routing documents and building email list servers is just the beginning. Harness the power of worldwide communication in your everyday business applications. MAPI is the cornerstone of messaging on the Windows platforms, and profoundly influences the way you will write your collaboration applications. Understanding this technology lays the foundation for adding effective collaboration capabilities to your own applications. CDO and MAPI Programming with Visual Basic: Developing Mail and Messaging Applications fills a gap in an exciting and relatively young, yet popular, technology that lacks adequate documentation.

    Abstract: This concise book contains detailed information about Oracle internals -- information that's not readily available to Oracle customers. It lays a foundation for advanced performance tuning of the Oracle database. Based on Oracle8i release 8.1, the book describes many of the secrets of Oracle's internal services: data structures, algorithms, and undocumented Oracle system statistics. Main topics include: Waits - how Oracle processes communicate via semaphores, and how to use the Oracle wait statistics to identify the source of performance problems. Latches - how they keep multiple processes from inspecting protected data structures at the same time, and how to examine and control latch behavior and statistics. Locks - how they work with latches to protect data structures (locks allow multiple sessions to share resources in some cases), and how locks affect performance. There is also a detailed discussion of instance locks, which are used in parallel server environments. Memory - how Oracle uses memory (e.g., the various elements of the System Global Area), and how Oracle dynamically allocates and manages memory. Oracle8i Internal Services is aimed especially at administrators and developers who need detailed internal information to do advanced performance tuning. The book will expand your repertoire of tuning solutions and troubleshooting techniques by explaining how you can use Oracle's hidden parameters and undocumented system statistics to best advantage. NOTE: The author has collected the scripts he has developed for tuning and analysis into a toolkit (known as APT, for Advanced Performance Tuning). These scripts access the Oracle X$ tables directly and provide information not otherwise available. The scripts are available to readers for free from the O'Reilly web site.

    Abstract: This book is the definitive guide to SQL*Plus. If you want to take best advantage of the power and flexibility of this popular Oracle tool, you need this book. SQL*Plus is an interactive query tool that is ubiquitous in the Oracle world. It is present in every Oracle installation and is available to almost every Oracle developer and database administrator. SQL*Plus has been shipped with Oracle since at least version 6. It continues to be supported and enhanced with each new version of Oracle, including Oracle8 and Oracle8i. It is still the only widely available tool for writing SQL scripts. Despite this wide availability and usage, few developers and DBAs know how powerful SQL*Plus really is. This book introduces SQL*Plus, includes a quick reference to all of its syntax options, and, most important, provides chapters that describe, in step-by-step fashion, how to perform all of the tasks that Oracle developers and DBAs want to perform with SQL*Plus -- and maybe some they didn't realize they COULD perform with SQL*Plus. You will learn how to write and execute script files, generate ad hoc reports, extract data from the database, query the data dictionary tables, customize your SQL*Plus environment, and use the SQL*Plus administrative features (new in Oracle8i). This book is an indispensable resource for readers who are new to SQL*Plus, a task-oriented learning tool for those who are already using it, and a quick reference for every user. A table of contents follows: Preface Introduction to SQL*Plus Interacting with SQL*Plus Generating Reports with SQL*Plus Writing SQL*Plus Scripts Extracting Data with SQL*Plus Exploring Your Database with SQL*Plus Advanced Scripting Tuning and Timing The Product User Profile Administration with SQL*Plus Customizing Your SQL*Plus Environment A.

    Abstract: This compact guide provides the jump-start Oracle developers need to make the transition from traditional programming to the development of useful Web applications for Oracle8i. Even readers who start out knowing nothing about HTML, PL/SQL, or Oracle's other tools will learn how to create simple Web applications in a matter of days. The book focuses on Oracle8i, but also covers Web development for earlier Oracle versions (Oracle8 and Oracle7). Background: The explosion in the use of the Internet and the Web has resulted in a whole new way of doing business. Developers who only yesterday were using COBOL to write accounts payable systems are now being asked to create a broad range of new Internet-based applications ranging from electronic commerce (e-commerce) Web sites to internal data warehouses to enterprise resource planning (ERP) systems. Unfortunately, the filesystem architectures of most Web systems aren't up to the task. The new breed of Web applications -- which are quickly becoming critical resources that companies need to survive -- demand a platform that provides production-quality tools for content management, application development, and application integration. And current Web techniques are inadequate in many ways. Oracle8i, Oracle's "Internet database," gives Web developers a way to build Web technology on top of a relational database, rather than on a traditional filesystem. With Oracle8i, companies can apply well understood, reliable, production-quality database methodologies to Web content management. Oracle8i also supports a wide variety of application development platforms and tools that are tightly integrated to the core database. Finally, Oracle8i supports technologies that help companies tie their Web-based applications into legacy applications. There is a lot to learn in Oracle8i. Not only does it enhance basic database features, it introduces Java and a variety of Web development tools. Oracle8i provides a soup-to-nuts platform for Web site and Web application development that extends traditional database concepts to Web content. It replaces the traditional filesystem used by most Web servers with a database management system. Many users are intimidated by the vast array of new technologies in Oracle8i. And yet, they are under pressure to use these technologies to build complex Web applications right now. This book gives such users a way to start using Oracle8i immediately to create useful Web applications. It is a co...

    Abstract: Oracle database administration requires a vast amount of information and an ability to perform a myriad of tasks--from installation to tuning to network troubleshooting to overall daily administration. Oracle provides many tools for performing these tasks; the trick is knowing what tool is right for the job, what commands you need to issue (and when), and what parameters and privileges you need to set. And, as every DBA knows, you need to know how do all this under pressure, while you face crisis after crisis. This book provides a concise reference to the enormous store of information an Oracle DBA needs every day (as well as what's needed only when disaster strikes). It's crammed full of quick-reference tables, task lists, and other summary material that both novice and expert DBAs will use time and time again. It covers the commands and operations new to Oracle8, but also provides Oracle7 information for sites still running earlier versions. Oracle Database Administration provides two types of material: DBA tasks--chapters summarizing how to perform critical DBA functions: installation, performance tuning, preventing data loss, networking, security and monitoring, auditing, query optimization, and the use of various Oracle tools and utilities DBA reference--chapters providing a quick reference to the Oracle instance and database, the initialization (INIT.ORA) parameters, the SQL statements commonly used by DBAs, the data dictionary tables, the system privileges and roles, and the SQL*Plus, Export, Import, and SQL*Loader syntax The book also includes a resource summary with references to additional books, Web sites, and other online and offline resources of special use to Oracle DBAs. Oracle Database Administration is the single essential reference you'll turn to again and again. If you must choose only one book to use at the office, keep at home, or carry to a site you're troubleshooting, this will be that book.

    Abstract: This pocket reference provides quick-reference information that will help you use Oracle's PL/SQL language. It is a companion to Steven Feuerstein and Bill Pribyl's bestselling book, Oracle PL/SQL Programming , and includes coverage of the latest version of Oracle, Oracle8i. Oracle is the most popular database management system in use today, and PL/SQL plays a pivotal role in current and projected Oracle products and applications. PL/SQL provides procedural extensions to the SQL relational database language and to an ever-growing number of Oracle development tools. It offers a myriad of data types, and such features as cursors, loops, conditional and sequential control statements, exception handlers, records, tables, and constructs for developing modular code (functions, procedures, and packages). Originally a rather limited tool, PL/SQL became with Oracle7 a mature and effective language for developers. Now, with the introduction of Oracle8, PL/SQL has taken the next step towards becoming a fully realized programming language providing sophisticated object-oriented capabilities. The book on which this pocket reference is based, Oracle PL/SQL Programming , filled a huge gap in the Oracle market, providing developers with a single, comprehensive guide to building applications with PL/SQL -- and building them the right way. That book has become the bible for PL/SQL developers who have raved about its completeness, readability, and practicality. The book is packed with strategies, code architectures, tips, techniques, and fully realized code. The second edition of the book updated the text with the new Oracle8 PL/SQL features, including object types, collections, external procedures, and large object data types and functions. The pocket reference boils down the most vital information from the large (nearly 1000 pages) book into an accessible quick reference that summarizes the basics of PL/SQL -- its block structure, fundamental language elements (e.g., identifiers, declarations, defaults), data structures (including Oracle8 objects), and statements for program control, loops, exception handling, and database access. It also covers the the basics of using Oracle's procedures, functions, and packages, and the latest features for Oracle8i.

    Abstract: Any organization that uses the Oracle relational database management system (RDBMS) these days needs to use multiple databases. There are many reasons to use more than a single database in a distributed database system: Different databases may be associated with particular business functions, such as manufacturing or human resources. Databases may be aligned with geographical boundaries, such as a behemoth database at a headquarters site and smaller databases at regional offices. Two different databases may be required to access the same data in different ways, such as an order entry database whose transactions are aggregated and analyzed in a data warehouse. A busy Internet commerce site may create multiple copies of the same database to attain horizontal scalability. A copy of a production database may be created to serve as a development test bed. Tunability Platform autonomy Fault tolerance Scalability Location transparency Site autonomy Introduction to Distributed Database Systems SQL*Net and Net8 Configuration and Administration Distributed Database Security Designing the Distributed System Oracle's Distributed System Implementation Sample Configurations 8. Engineering Considerations Oracle Replication Architecture Advanced Replication Option Installation Basic Replication Multi-Master Replication Updateable Snapshots Procedural Replication Conflict Avoidance and Resolution Techniques In a distributed database environment, data in two or more databases is accessible as if it were in a single database. Usually, the different databases are on different servers, which may be located at the same site or a continent away. Communication between the servers takes place via SQL*Net (for Oracle7) or Net8 (for Oracle8). Distributed database environments offer a number of benefits over single- database systems, including: This book describes how you can use multiple databases and the distributed features of Oracle to best advantage.

    Abstract: As the application of object technology--particularly the Java programming language--has become commonplace, a new problem has emerged to confront the software development community. Significant numbers of poorly designed programs have been created by less-experienced developers, resulting in applications that are inefficient and hard to maintain and extend. Increasingly, software system professionals are discovering just how difficult it is to work with these inherited, "non-optimal" applications. For several years, expert-level object programmers have employed a growing collection of techniques to improve the structural integrity and performance of such existing software programs. Referred to as "refactoring," these practices have remained in the domain of experts because no attempt has been made to transcribe the lore into a form that all developers could use. . .until now. In Refactoring: Improving the Design of Existing Code, renowned object technology mentor Martin Fowler breaks new ground, demystifying these master practices and demonstrating how software practitioners can realize the significant benefits of this new process. With proper training a skilled system designer can take a bad design and rework it into well-designed, robust code. In this book, Martin Fowler shows you where opportunities for refactoring typically can be found, and how to go about reworking a bad design into a good one. Each refactoring step is simple--seemingly too simple to be worth doing. Refactoring may involve moving a field from one class to another, or pulling some code out of a method to turn it into its own method, or even pushing some code up or down a hierarchy. While these individual steps may seem elementary, the cumulative effect of such small changes can radically improve the design. Refactoring is a proven way to prevent software decay. In addition to discussing the various techniques of refactoring, the author provides a detailed catalog of more than seventy proven refactorings with helpful pointers that teach you when to apply them; step-by-step instructions for applying each refactoring; and an example illustrating how the refactoring works. The illustrative examples are written in Java, but the ideas are applicable to any object-oriented programming language.

    Abstract: Java's most striking claim is that it provides a secure programming environment. However, despite lots of discussion, few people understand precisely what Java's claims mean and how it backs up those claims. Java Security is an in-depth exploration aimed at developers, network administrators, and anyone who needs to work with or understand Java's security mechanisms. It discusses in detail what security does and doesn't mean, what Java's default security policies are, and how to create and implement your own policies. In doing so, Java Security provides detailed coverage of security managers, class loaders, the access controller, and much of the java.security package. It discusses message digests, certificates, and digital signatures, showing you how to use Java's facilities for signing classes or to implement your own signature facility. It shows you how to write a class loader that recognizes signed classes, verifies the signature, and cooperates with a security manager to grant additional privileges. It also discusses the problem of managing cryptographic keys and shows you how to implement your own key management systems. Java Security is an essential book for everyone using Java in real-world software. If you're deploying software written in Java, you need to know how to grant your classes the privileges they need, without granting privileges to untrusted classes. You need to know how to protect your systems against intrusion and corruption. Java provides the tools; this book shows you how to use them.

    Abstract: Oracle is the most popular database management system in use today, and PL/SQL plays a pivotal role in current and projected Oracle products and applications. PL/SQL is a programming language providing procedural extensions to the SQL relational database language and to an ever-growing number of oracle development tools. originally a rather limited tool, PL/SQL became with Oracle7 a mature and effective language for developers. now, with the introduction of Oracle8, PL/SQL has taken the next step towards becoming a fully realized programming language providing sophisticated object-oriented capabilities. Steven Feuerstein's Oracle PL/SQL Programming is a comprehensive guide to building applications with PL/SQL. That book has become the bible for PL/SQL developers who have raved about its completeness, readability, and practicality. Built-in packages are collections of PL/SQL objects built by Oracle Corporation and stored directly in the Oracle database. The functionality of these packages is available from any programming environment that can call PL/SQL stored procedures, including Visual Basic, Oracle Developer/2000, Oracle Application Server (for web-based development), and, of course, the Oracle database itself. Built-in packages extend the capabilities and power of PL/SQL in many significant ways. for example: DBMS_SQL executes dynamically constructed SQL statements and PL/SQL blocks of code. DBMS_PIPE communicates between different Oracle sessions through a pipe in the RDBMS shared memory. DBMS_JOB submits and manages regularly scheduled jobs for execution inside the database. DBMS_LOB accesses and manipulates Oracle8's large objects (LOBs) from within PL/SQL programs. 1. Introduction Executing Dynamic SQL and PL/SQL Intersession Communication User Lock and Transaction Management Oracle Advanced Queuing Generating Output from PL/SQL Programs Defining an Application Profile Managing Large Objects Datatype Packages Miscellaneous Packages Managing Session Information Managing Server Resources Job Scheduling in the Database Snapshots Advanced Replication Conflict Resolution Deferred Transactions and Remote Procedure Calls The first edition of Oracle PL/SQL Programming contained a chapter on Oracle's built-in packages. but there is much more to say about the basic PL/SQL packages than Feuerstein could fit in his first book. In addition, now that Oracle8 has been released, there are many new Oracle8 built-in packages not described in the PL/SQL...

    Abstract: Steven Feuerstein's first book, Oracle PL/SQL Programming , has become the classic reference to PL/SQL, Oracle's procedural extension to its SQL language. His new book looks thoroughly at one especially advanced and powerful part of the PL/SQL language -- the package. The use of packages can dramatically improve your programming productivity and code quality, while preparing you for object-oriented development in Oracle technology. In this book, Feuerstein explains how to construct packages -- and how to build them the right way. His "best practices" for building packages will transform the way you write packages and help you get the most out of the powerful, but often poorly understood, PL/SQL language. Much more than a book, Advanced Oracle PL/SQL Programming with Packages comes with a PC diskette containing a full-use software companion. Developed by Feuerstein, RevealNet's PL/Vision Lite is the first of its kind for PL/SQL developers: a library of thirty-plus PL/SQL packages. The packages solve a myriad of common programming problems and vastly accelerate the development of modular and maintainable applications. The packages provided in PL/Vision Lite fall into three categories: Building block packages: low-level development enhancers, including string parsers, a list manager, and an interface to PL/SQL tables. Developer utilities: programs that improve your PL/SQL development environment, including a code generator, a powerful substitute for SHOW ERRORS, and an online help delivery mechanism. Plug-and-play components: pieces of code that can be used as is in your own applications, including a high-level exception handler mechanism and a generic, reusable logging mechanism. In addition to describing the details of these packages, this book explores why and how they were built the way they were. You'll come away with an increased appreciation of the PL/SQL language and the power of packages. Most importantly, you'll be ready and eager to put that power to use immediately in your own applications.

    Abstract: Upon completion of an object-oriented design, you are faced with a troubling question: "Is it good, bad, or somewhere in between?" Seasoned experts often answer this question by subjecting the design to a subconscious list of guidelines based on their years of experience. Experienced developer Arthur J. Riel has captured this elusive, subconscious list, and in doing so, has provided a set of metrics that help determine the quality of object-oriented models. Object-Oriented Design Heuristics offers insight into object-oriented design improvement. The more than sixty guidelines presented in this book are language-independent and allow you to rate the integrity of a software design. The heuristics are not written as hard and fast rules; they are meant to serve as warning mechanisms which allow the flexibility of ignoring the heuristic as necessary. This tutorial-based approach, born out of the author's extensive experience developing software, teaching thousands of students, and critiquing designs in a variety of domains, allows you to apply the guidelines in a personalized manner. The heuristics cover important topics ranging from classes and objects (with emphasis on their relationships including association, uses, containment, and both single and multiple inheritance) to physical object-oriented design. You will gain an understanding of the synergy that exists between design heuristics and the popular concept of design patterns; heuristics can highlight a problem in one facet of a design while patterns can provide the solution. Programmers of all levels will find value in this book. The newcomer will discover a fast track to understanding the concepts of object-oriented programming. At the same time, experienced programmers seeking to strengthen their object-oriented development efforts will appreciate the insightful analysis. In short, with Object-Oriented Design Heuristics as your guide, you have the tools to become a better software developer. 020163385XB04062001

    Abstract: Inside the C++ Object Model focuses on the underlying mechanisms that support object-oriented programming within C++: constructor semantics, temporary generation, support for encapsulation, inheritance, and "the virtuals"--virtual functions and virtual inheritance. This book shows how your understanding the underlying implementation models can help you code more efficiently and with greater confidence. Lippman dispells the misinformation and myths about the overhead and complexity associated with C++, while pointing out areas in which costs and trade offs, sometimes hidden, do exist. He then explains how the various implementation models arose, points out areas in which they are likely to evolve, and why they are what they are. He covers the semantic implications of the C++ object model and how that model affects your programs. Highlights Explores the program behavior implicit in the C++ Object Model's support of object-oriented programming. Explains the basic implementation of the object-oriented features and the trade offs implicit in those features. Examines the impact on performance in terms of program transformation. Provides abundant program examples, diagrams, and performance measurements to relate object-oriented concepts to the underlying object model. If you are a C++ programmer who desires a fuller understanding of what is going on "under the hood," then Inside the C++ Object Model is for you! Get a value-added service!
