1、摘摘 要要 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（Unified Modeling Language，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。到今天 UML 差不多已经成为建模语言的事实标准。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。 关键词：关键词：UML COM+

The UML (Unified Modeling Language) is one of they. In addition, its a popular and Object-Oriented based model languag
3、e. The UML has almost been the international standard of model language. Using 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 lots of tools and program languages are used, such as Delphi, VBScript, ADO, XML, and HTML etc. Key Words：UML COM+ Delphi ASP ADO XML 目 录 分布式网络考试系统原型分析及实现 错误错误!未定义书签。未定义书签。 1. 问题定义 4 2. 需求分析
