摘要
通过统一建模语言(UML)对网络考试系统进行了分析和建模,建立了系统用例图,并结合主要用例—学生考试模块,建立了类图、顺序图、活动图.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在线考试系统.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.
In this paper a network examination system has been analyzed and modeled by the unified modeling language （UML）. The use case diagrarn, class diagram, sequence diagram and activity diagram for the examination use case of students have boen constructed. The function requirement and function flow, instructions and relations of class, and interaction and communication between objects are described as well. Finally, f＇mish the code and realize the system object oriented program language. In the way to model the system, process is optimized and the stability, maintainability and reusability are imoroved.
