Preface
SQL: The Complete Reference provides a comprehensive, in-depth treatment of the SQL language for both technical and non-technical users, programmers, data processing professionals, and managers who want to understand the impact of SQL in the computer market. This book offers a conceptual framework for understanding and using SQL, describes the history of SQL and SQL standards, and explains the role of SQL in the computer industry today. It will show you, step-by-step, how to use SQL features, with many illustrations and realistic examples to clarify SQL concepts. The book alsocompares SQL products from leading DBMS vendors ? describing their advantages, benefits, and trade-offs ? to help you select the right product for your application. The accompanying CD contains actual trial versions of five leading SQL databases, so you can try them for yourself and gain actual experience in using major database products from Oracle, Microsoft, Sybase, Informix, an IBM. In some of the chapters in this book, the subject atter is explored at two different levels— a fundamental description of the topic, and an advanced discussion intended for computer professionals who need to understand some of the "internals" behind SQL. The more advanced information is covered in sections marked with an asterisk (*). You do not need to read these sections to obtain an understanding of what SQL is and what it does.
