摘要
介绍了一个基于NET平台的远程考试系统框架。首先是在领域逻辑层中,采用创建型模式控制易于产生变化的试卷对象的创建工作,采用策略模式控制生成试题的参数与规则;然后是在Web层中,通过把试题对象的表现与数据分离,定义了Web层与业务外观层交互的接口,并且把与用户交互的多媒体信息封装到特定的UI控件中,最后分析了数据访问层中的对象--关系映射问题;从而得到了一个灵活的、可重用的考试系统框架。
This paper presents a remote test system framework ba se d on.NET platform. We first apply creational pattern in domain logic layer to co ntrol the creation process of the test paper object that may changeful, Strategy pattern is used to control the parameters and rulers that build the questions; Next we define the interface and collaboration between business facade layer and presentation layer (Web layer) through separating the data and presentation of the question object, Also, the multi-media information that interact with the us er is encapsulated in specific web controls;Then we analysis the O-R Mapping pro blem in the data access layer; Finally, we achieve a Remote Test System Framewor k that is both flexible and Reusable.
