用统一建模语言描述基于构件的系统

Represent Component-based System Using UML

通常基于构件的系统和CORBA ,ActiveX/COM/DCOM ,JavaBeans等具体的技术相紧密结合。提出一种用对象建模语言描述构件及其接口的表示方法 ,这种构件的表示方法能用现有技术实现 ,而又不依赖于某种特定技术的方法和开发工具。先给出构件、接口和基于构件开发的概念 ,然后介绍统一建模语言对构件及其接口的建模和构造原则 ,以及用统一建模语言描述基于构件的系统的方法。

Often Component-based System is immediately associated with a specific technology: CORBA, Microsoft ActiveX/COM/DCOM, Java Beans, etc. This paper propose a represent method using the Unified Modeling Language (UML) to represent component and interface, this method can be instantiated in any of technologies, but it still be independent from a specific technology. We give our definition of component, interface and component-based development in this paper, then introduce the component modeling principle and show how to represent component-based system using UML.
