    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.

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. It covers: Table of contents: Part I: The Distributed System Part II: Replication Part III: Appendixes Appendix A: Built-in Packages for Distributed Systems Appendix B: Scripts

    Abstract: When using software products with graphical interfaces, we frequently focus so much on the details of how to use the interface that we forget about the more general concepts that allow us to understand and put the software to effective use. This is particularly true of a powerful database product like Microsoft Access. Novice, and sometimes even experienced, programmers are so concerned with how something is done in Access that they often lose sight of the general principles that underlie their database applications. Access Database Design & Programming, 2nd Edition, an update to the bestselling first edition, features: A discussion of Access' new VBA Integrated Development Environment, which, for the first time, is the one used by Word, Excel, and PowerPoint An expansion of the discussion of the VBA language itself, in response to reader requests A discussion of Microsoft's latest data access technology, called Active Data Objects (or ADO), along with a discussion of Open Database Connectivity(ODBC), which is intimately connected with ADO Unlike other Access books that take the long, detailed approach to every topic of concern to Access programmers, this book focuses instead on the core concepts, enabling programmers to develop solid, effective database applications. As a result, important topics such as designing forms and reports, database security, database replication, and programming for multiuser applications are simply not discussed. This book is a kind of "second course" in Access that provides a relatively experienced Access user who is new to programming with the frequently overlooked techniques necessary to successfully develop in the Microsoft Access environment. Anyone interested in learning Access in-depth, rather than just scraping the surface, will enjoy and immensely benefit from reading this book. Although this book is really an introduction directed to intermediate Microsoft Access users who are novice programmers, it should appeal to all levels of Access developers. For novice programmers, it focuses on a key body of knowledge that is typically neglected, but is nevertheless essential for developing effective database applications. For intermediate and advanced developers, its treatment of database design and queries provides a handy treatment that otherwise has to be gleaned from relatively uninteresting textbooks, while its programming chapters constitute a handy reference to some basic operations that can be perform...

    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: There are lots of introductory C books, but this is the first one that has the no-nonsense, practical approach that has made Nutshell Handbooks(R) famous.C programming is more than just getting the syntax right. Style and debugging also play a tremendous part in creating programs that run well and are easy to maintain. This book teaches you not only the mechanics of programming, but also describes how to create programs that are easy to read, debug, and update.Practical rules are stressed. For example, there are fifteen precedence rules in C (&& comes before comes before ?:). The practical programmer reduces these to two: Multiplication and division come before addition and subtraction. Contrary to popular belief, most programmers do not spend most of their time creating code. Most of their time is spent modifying someone else's code. This books shows you how to avoid the all-too-common obfuscated uses of C (and also to recognize these uses when you encounter them in existing programs) and thereby to leave code that the programmer responsible for maintenance does not have to struggle with. Electronic Archaeology, the art of going through someone else's code, is described.This third edition introduces popular Integrated Development Environments on Windows systems, as well as UNIX programming utilities, and features a large statistics-generating program to pull together the concepts and features in the language.

    Abstract: sed & awk describes two text processing programs that are mainstays of the UNIX programmer's toolbox. sed is a "stream editor" for editing streams of text that might be too large to edit as a single file, or that might be generated on the fly as part of a larger data processing step. The most common operation done with sed is substitution, replacing one block of text with another. awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts.This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk , where POSIX standardized a new variable, CONVFMT, and new functions, toupper () and tolower (). The CONVFMT variable specifies the conversion format to use when converting numbers to strings ( awk used to use OFMT for this purpose). The toupper () and tolower () functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case.In addition, this edition covers GNU sed , newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk ( gawk ), covers mawk , an additional freely available implementation of awk , and briefly discusses three commercial versions of awk , MKS awk , Thompson Automation awk ( tawk ), and Videosoft (VSAwk).

    Abstract: Once a little-known productivity boost for personal computers, Linux is now becoming a central part of computing environments everywhere. This operating system now serves as corporate hubs, Web servers, academic research platforms, and program development systems. All along it's also managed to keep its original role as an enjoyable environment for personal computing, learning system administration and programming skills, and all-around hacking. This book, now in its third edition, has been widely recognized for years in the Linux community as the getting-started book people need. It goes into depth about configuration issues that often trip up users but are glossed over by other books. A complete, UNIX-compatible operating system developed by volunteers on the Internet, Linux is distributed freely in electronic form and at a low cost from many vendors. Developed first on the PC, it has been ported to many other architectures and can now support such heavy-duty features as multiprocessing, RAID, and clustering. Software packages on Linux include the Samba file server and Apache Web server; the X Window System (X11R6); TCP/IP networking (including PPP, SSH, and NFS support); popular software tools such as Emacs and TeX; a complete software development environment including C, C++, Java, Perl, Tcl/Tk, and Python; libraries, debuggers, multimedia support, scientific and database applications, and much more. Commercial applications that run on Linux range from end-user tools like word processors and spreadsheets to mission-critical software like the Oracle, Sybase, Informix, and IBM DB/2 database management systems. Running Linux has all the information you need to understand, install, and start using the Linux operating system. This includes a comprehensive installation tutorial, complete information on system maintenance, tools for document development and programming, and guidelines for network, file, printer, and Web site administration. New topics in the third edition include: KDE, a desktop that brings the friendliness and ease-of-use of Windows or the Macintosh to Linux Samba, which turns Linux into an office hub that serves files and printers to Microsoft systems PPP, the most popular software for logging into remote systems over phone lines Revised instructions for installation and configuration, particularly covering the Red Hat, SuSE and Debian distributions
