内容简介
重构已经在众多领域的开发项目中证明了其自身的价值――帮助软件专业人士改善系统的设计、可维护性、可扩展性和性能。如今，世界一流的敏捷方法理论家Scott W. Ambler和著名咨询顾问Pramod J. Sadalage首次披露了为数据库系统专门设计的强大的重构技术。.Ambler和Sadalage展示了如何在不改变语义的情况下，对表结构、数据、存储过程及触发器等略作改动，就可以给几乎任何数据库设计带来实质上的飞跃。读者将学会如何让数据库模式与源代码同步渐进――从而依靠迭代的敏捷方法在项目中发挥更多的作用。这是一本内容全面的参考、指南书，全面介绍了数据库重构涉及的每个基本观念，可以帮助读者克服重构数据库所遇到的实际困难。本书作者运用完整的实例，带领读者学习从重构简单的孤立数据库应用程序到重构复杂的多应用程序环境的全过程。读者将掌握与重构数据库模式有关的全部任务，找到最佳的方法，将重构的结果布置到哪怕是最复杂的产品环境中。..本书第二部分系统讲述了数据库重构的五大主要类别。读者将学会如何运用重构改善数据库结构、数据质量和参照完整性，如何同时对结构和方法进行重构。本书提供了用Oracle和Java建立的多种实例，可以方便地转换成C#、C++、VB.NET等其它语言或DB2、SQL Server、MySQL、Sybase等其他数据库。本书适合数据库设计、开发、维护人员及数据库技术爱好者。...
