【摘要】 针对传统数据库访问中出现的业务逻辑和数据访问逻辑混杂、程序复用程度低以及难以维护的弊端,阐述了怎样利用几种常用的设计模式来设计一个数据持久层框架的解决方案,并给出了部分实现代码。该框架有效地提高了代码的可重用性和可扩展性,有一定的实用价值。更多还原

【Abstract】 Aiming at the shortage in traditional database access,such as intermixing of business logic and data access logic\difficulty in reusing and maintaining the programs,the realizing scheme of how to use some common design patterns to design a data persistence fra-mework was discussed to solve the problem,and part of the implementation codes was given.This framework effectively improves the code reusability and extensibility and has definite practical value.更多还原
