内容简介:
本书对当前存在的数据库系统的诸多领域进行了全面的介绍。它为数据库技术的建立提供了坚实的基础，同时还展望了未来该领域的发展前景。此最新版本对原版本进行了扩充和更新，以紧跟数据库系统发展和开发的趋势；不过，全书的重点仍然放在使读者掌握和理解相关知识上，而不是让内容流于形式。
重点包括：
SQL部分的内容已经更新到当前标准。
广泛覆盖并延伸了对关系模型内容的介绍。
关于类型或域的资料已经归类到其各自的章节。
第9章内容已经完全重写。
充分修订、扩充、改进了第15章和第16章的内容，包括了对事务的ACID特性的仔细分析以及有关于此的一些争议
第20章和第23章的内容已经完全重写，以反映当前的研究进展。
第27章涉及数据库与新兴XML标准之间的关系。
附录的内容也重新编写过，以包括如下内容：
TransRelational TM Model综述。
SQL表达式的BNF语法。
一些重要的缩写词以及文中符号的术语表。
作者简介：
