具体描述
For courses in Database Management. Focusing on standard ANSI SQL with a learn-by-doing approach, this text organizes SQL subtopics into short chapters. Students first learn the features of a SQL command, then its usage, based on management questions that typically arise in the management decision-making process. The authors pose management questions and then give examples of how SQL can be used to provide the data needed. In light of the wide adoption of the Oracle relational DBMS product in academic institutions and industry, additional examples of the supplemental commands available in the Oracle implementation of SQL are provided. All of the SQL concepts and commands covered (except in SQL *Plus and PL/SQL) are equally applicable to database management system software that follows the ANSI SQL standard--including DB2, SQL Server, and SYBASE.
