设计模式在CAS系统的数据库引擎中的应用

Using Design Pattern in CAS System Database Engine

设计模式以及基于设计模式的软件系统开发是高级软件复用技术,它的成功设计带来的不仅仅是表面上的代码模块的可重复利用,对设计理念的变更,而且对减少程序的自身缺陷有巨大的作用。文中以采用设计模式设计的一个高效数据库引擎为例子,阐明设计模式对大系统的项目所带来的可复用性的优势。

Design Pattern and the software system development based on it are advanced software reusable techniques. Its success brings not only the reusability of code modules, but also a paradigm shift in design. Furthermore it helps greatly in reducing the defects in programs. This paper proposes an efficient database engine built with design pattern techniques, and demonstrates the reusability benefits of such techniques in large scale system.
