基于网络的计算机等级考试系统的UML建模

UML Modeling of Computer Rank Examination System Based on Internet

文中通过统一建模语言(UML)描述网络考试系统的建模过程,并对其进行需求分析、总体设计和详细设计。以题库制作模块为例建立了系统用户模型、静态模型和动态模型的各种视图和规范化文档,描述了系统的功能需求、功能流程、类的结构与关系、对象之间的交互。最终采用面向对象语言实现计算机等级考试系统。使用这种方法对系统进行建模,优化了开发过程,并有利于提高系统的稳定性、可维护性和可重用性。

Modeling process of the computer rank examination system on intemet is described by the unified modeling language （UML）, and requirement analysis, general design and retailed design are also made. At the same time, taking the test bank making subsystem as an example, various view and standard documents such as systematic user model, static model and dynamitic model etc are built up. The function requirement and function flow, instructions and relations of classification and interaction and communication between objects are described as well. Finally, finish the code and realize the system by object oriented program language. In the way to model the system, process is optimized and the stability, maintainability and reusability are improved.
