基于UML的在线考试系统的软件建模

Software Model of the Online Test System Based on the UML

目前国内网络化考试系统大都存在功能少、扩展性差、使用局限性大、不能确保考试质量等不足,这与实际考试方式计算机化,考试管理网络化还有很大的差距。在研究高校考试命题方法、管理和网络考试系统的基础上,对在线考试系统进行需求分析,应用UML分析设计B/S结构的系统模型,有利于提高系统的稳定性、可维护性和可重用性。

In order to avoid the disadvantages of the traditional test,to improve test efficiency and reduce test service burden,realization paperless test has become a development trend of the college test service.With the network popularization by means of informatization method,online test is more significant advantages,but at present domestic online test systems there are many deficiencies of less functional,poor scalability,too limita-tion,test quality uncertainty,which is still a big gap comparing with the online test and network management. The essay is based on the research of college test method,management and the network test system,carries on the requirement analysis and requirement modeling to the online test system,and makes use of UML to model and design for it.The system model of B/S structure used the UML analysis and design,can improve the sys-tem stability,reusability and maintainability,and provides a means of communication.
