Absolute Beginner's Guide to Databases brings the elements of a database together using easy to understand language, perfect for the true beginner. It not only gives specific hands on practice, but also provides an overview of designing, maintaining and using a database. This book covers what databases are used for, why databases are important, why the design of the database is important, database normalization, keys to solid database design, differences in types of databases, and indexes--what they are, how we use them, and why they are important.

Arguably the most capable of all the open source databases, PostgreSQL is an object-relational database management system first developed in 1977 by the University of California at Berkeley. In spite of its long history, this robust database suffers from a lack of easy-to-use documentation. Practical PostgreSQL fills that void with a fast-paced guide to installation, configuration, and usage. This comprehensive new volume shows you how to compile PostgreSQL from source, create a database, and configure PostgreSQL to accept client-server connections. It also covers the many advanced features, such as transactions, versioning, replication, and referential integrity that enable developers and DBAs to use PostgreSQL for serious business applications. The thorough introduction to PostgreSQL's PL/pgSQL programming language explains how you can use this very useful but under-documented feature to develop stored procedures and triggers. The book includes a complete command reference, and database administrators will appreciate the chapters on user management, database maintenance, and backup & recovery. With Practical PostgreSQL, you will discover quickly why this open source database is such a great open source alternative to proprietary products from Oracle, IBM, and Microsoft.

PostgreSQL is an object-relational database server that is widely considered to be the world¿s most advanced open-source database system. It is ANSI SQL-compatible, and it offers powerful features to enable more complex software design than would be possible with relational databases that are not object-oriented. PostgreSQL is extremely modular, it supports a large number of datatypes, and programming interfaces for PostgreSQL are available for all important programming languages, including C, Perl, Python, Tcl, Java, and PHP. PostgreSQL Developer¿s Handbook provides a complete overview of the PostgreSQL database server and extensive coverage of its core features, including object orientation, PL/pgSQL, and the most important programming interfaces. The book introduces the reader to the language and syntax of PostgreSQL and then moves quickly into advanced programming topics.

This IBM Redbooks publication gives you information to use the IBM Enterprise Storage Subsystem with IBM DB2 Universal Database. Most of the information presented here applies to UNIX and Windows environments. Our examples are only for AIX. First, we supply an overview of the products that we use in our environment and introduce the terminology. Next, we discuss the configuration options available for these products and the methodology that we recommend for sizing an Enterprise Storage Subsystem for use with the DB2 Universal Database. We also discuss the challenges of mapping the system resources to the database activity in an ESS environment, and we discuss the diagnostic tools which are available and how to use them when working with performance issues. Then we discuss backup and recovery and explain some of the new features available with DB2 UDB V7.2, which enable some of the ESS capabilities. Last, we include our test examples. This book is intended to be read by systems administrators, storage specialists, database administrators and database specialists. We assume a base knowledge of either: ESS, AIX and/or DB2 and intend that this book will help you understand your area of expertise in a wider context.

Applications are fully explained so you can understand how they work and apply the techniques they illustrate to your own projects.

MySQL: Designing User Interfaces starts by introducing the functionality of GTK+ and how to migrate from Microsoft's Visual Basic. It then introduces MySQL as a simple, fast, reliable database for corporate applications. The book then flows into the how-to of combining GTK+ and MySQL through the coverage of the C API for MySQL because it is the "backend" to a GTK+ application. It then expands its coverage and teaches about heterogeneous network and deployment issues, as well as migration from existing systems to MySQL.

In MySQL, Paul DuBois provides you with a comprehensive guide to one of the most popular relational database systems. As an important contributor to the online documentation for MySQL, Paul uses his day-to-day experience answering questions users post on the MySQL mailing list to pinpoint the problems most users and administrators encounter. The principal MySQL developer, Monty Widenius, along with a network of his fellow developers, reviewed the manuscript, providing Paul with the kind of insight no one else could supply. Instead of merely giving you a general overview of MySQL, Paul teaches you how to make the most of its capabilities. Through two sample databases that run throughout the book, he gives you solutions to problems you'll likely face. He helps you integrate MySQL efficiently with third-party tools, such as PHP and Perl, enabling you to generate dynamic Web pages through database queries. He also teaches you to write programs that access MySQL databases.
