基于实体框架集的自主招生管理系统研究

Research of Informantion Management System of Independent enrolment Based on Entity Framework

为了结合多层架构系统、工作单元模式、资源库模式的优点,减少数据访问的复杂性,提出了将ADO.NET实体框架集与多层架构、工作单元模式、资源库模式相融合的方法。该方法屏蔽了底层数据访问的复杂性,实现了业务实体强类型化,使得在数据访问层以一致的方式完成数据存取和传递,同时便于各层之间的协调。在某高校自主招生管理系统中使用ADO.NET实体框架集技术实现了应用程序与数据库之间的交互并给出了资源库类图、工作单元的实现。

In order to employ the advantages of multi-layer architecture,unit of work pattern,repository pattern, reduce the complexity of the data access, puts forward the method of combining the ado.net entity framework and multi-layer architecture, unit of work pat- tern,repository pattern. The method of blocking the complexity of the data access, realize strong stereotype business entity, make data access and transmission with a consistent way to complete, facilitate between each layer of coordination at the same time. In a col- lege independent enrolment management system using the ADO,NET Entity Framework technology to achieve the interaction between the database and the application and give repository class diagram and the implement of the unit of work .
