| 摘 要： | 在开发在线考试系统的过程中，选择了B／S结构，并采用了典型的三层架构模型，这其中包括了数据层。利用存储过程来实现数据层服务，以及构造数据服务层的基类，在NET平台下实现统一的数据操作的入口。并阐述了在NET下如何利用该类实现操作存储过程，以便充分利用存储过程的优点来进行数据层服务，能够很大程度上提高程序的运行效率，并且在本系统中所有的数据底层操作都可以用该类来进行，维护和升级很方便，并且可以最大限度的复用．能方便的扩充底层数据操作。

| Abstract: | In the course of development of online examination system, the B/S structure and the typical 3-layer model including data layer are adopted. The dissertation emphasizes on how to make use of storing process to realize data layer service through storage, base class in constructing the data service layer, and entry to the unified data operation based on .net platform. And it has further explained how to realize the storing of operation through base-class and utilize the advantages of storing for data layer service. All that could improve operational efficiency of program and enable base-class to work in operation of all DBbase in development of online examination system, which could be easily maintained, updated and reused maximally, and the data in base would be enlarged conveniently. It might be useful in the course of development of information system. |
