内容説明

Giving comprehensive coverage of all aspects of SQL programming, this student-friendly text adopts a user-oriented approach. It covers the design of databases using both the E/R model and the OO standard ODL, and explains object-oriented and object-relational database programming. It also covers the OO standard OQL and object-oriented features of SQL3, and advanced database programming, including integrity constraints, assertions, triggers and recursion in SQL3.
