网络考试系统分析及实现

ANALYSIS AND REALIZATION OF ONLINE TEST SYSTEM

软件工程在现代软件开发中的作用越来越大,并且发展出了很多行之有效的软件工程方法和建模语言.UML(UnifiedModelingLanguage,统一建模语言)是一种非常流行的,支持面对对象建模方法的建模语言.本文就采用面对对象的方法以UML为建模语言,使用PowerDesigner这个case工具分析设计一个分布式的B/S结构的基于COM+和XML的网络考试系统.并使用Delphi,VBScript,ADO,XML,HTML等编程工具、语言和技术实现了这个系统.

Software engineering becomes more and more important in the modern software development. There are many functions and many software engineering methods. The UML (Unified Modeling Language) is one of them. In addition, it is a popular and object-oriented based model language. With object-oriented model and UML by case tools of PowerDesigner, the paper designs a distributed B/S constructed online test system, which is based on COM+ and XML. In order to realize the system, a lot of tools and program languages are used, such as Delphi, VBScript, ADO, XML, and HTML etc.
