• PostgreSQL: Introduction and Concepts - POSTGRESQL is the most advanced open source database server. In this chapter, you will learn about databases, open source software, and the history of POSTGRESQL. Three basic office productivity applications exist: word processors, spreadsheets, and databases. Word processors produce text documents critical to any business. Spreadsheets are used for financial calculations and analysis. Databases are used primarily for data storage and retrieval. You can use a word processor or spreadsheet to store small amounts of data. However, with large volumes of data or data that must be retrieved and updated frequently, databases are the best choice. Databases allow orderly data storage, rapid data retrieval, and complex data analysis.
• Practical PostgreSQL - PostgreSQL is one of the most successful open source databases available. It is arguably also the most advanced, with a wide range of features that challenge even many closed-source databases. This book is intended to be a practical guide to PostgreSQL v7.1.x, though most of the book should also apply to earlier and future releases of PostgreSQL. The content is focused on getting you comfortable with PostgreSQL in the most expedient fashion possible. Although we will touch on some academic database subjects, such discussion will be kept brief. Our core focus is to provide the reader with enough of an understanding of PostgreSQL to manage a fully operational PostgreSQL database. Our hope is that by introducing this book to the community we will provide a better understanding of PostgreSQL and its functionality.
