摘要
针对三层架构存在的缺陷,提出一种五层开发框架的设计方法.采用MVC设计模式引入了控制器,该控制器降低了表示层和业务逻辑层之间的耦合度;通过ORM技术增加了数据持久层,解决了关系数据模型和面向对象模型之间的"阻抗不匹配"问题.
In order to solve the defects that consist in 3-tier application,a design method of 5-tier application is presented. By using MVC design pattern we introduced the Controller which can reduce the cupling between UI and BLL, while, by using the technology of ORM we add the tier of Data Persistence which can solve the problem of impedance mismatch between Relation Data Model and Object Oriented Model.
