The authors begin by explaining how to design efficient data structures, an important part of database management. From there, they discuss how to populate a database with pieces of data and then explain how to construct queries that extract needed information. Throughout, the text is filled with statements, code, and output--and even common SQL errors. You ought to be able to follow along on any ANSI SQL 92-compliant system as you read this book.
Later chapters cover reports, joins, views, subqueries, and security. The authors explain each from a practical point of view. A section on common business-database tasks (how to specify decimal precision, for example) confirms this point of view. A good glossary exists in the back of this book, and a comprehensive table documents the differences among Sybase, Microsoft, Informix, and Oracle SQL command sets. The companion CD-ROM contains the Sybase SQL Anywhere Studio software, which ordinarily requires a 15-megabyte download marathon. --David Wall
