基于UML的高校选课系统优化分析

University Course Selection System Optimization Analysis Based on UML

为解决选课管理系统中安全性低和信息拥堵的问题,运用UML(Unified Modeling Language)建模方法,结合网上选课的主要流程和系统用户实际需求,通过Rational Rose 2003对高校选课系统进行了优化分析和设计,并以此构建了系统的用例图、类图、活动图、序列图、组件图和部署图。UML建模应用表明,该方法产生的模型易于理解,便于系统修改与升级,取得了很好的开发效果,从而克服了传统方法可扩充性低的问题。

To solve the problem of security vulnerabilities and information congestion in course selection management system, we used UML （Unified Modeling Language） modeling approach and combined with the main process of the online courses and the actual needs of users of the system to analyze and design course selection system by Rational Rose 2003. And we built the systems＇ use case diagram, class diagram, activity diagram, sequence diagram, component diagram and deployment diagram. UML modeling application shows that this method is easy to understand, to change and to upgrade. And this method has achieved a good development effect, overcome the low scalability of the traditional method.
