摘要: 通过研究MVC等开发模型, 提出了一种在分层开发模式下引入数据访问模型的设计方法, 该方法用于屏蔽表示层开发者对底层数据库的依赖性, 设计了数据访问模型构造器, 加快了程序开发的进度, 节约了程序开发过程中的人力、物力和时间, 且能够快速响应用户的需求.应用实例表明该方法简单有效, 具有较强的实用性.Abstract: Through the research on MVC model for development, this paper put forward a preliminary ideology about Data Access Model in the hierarchical development mode, Data Access Model used in shielding that of dependence for the developer in presentation layer.It expedites progress and saves man-power, material and time in the application development, and able to respond quickly to the needs of users.The experiments demonstrate that the proposed algorithm is simple, efficient and practicable.
