Abstract:

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.

Key words: unified modeling language（UML）, object-oriented, elective system
