摘要： 遗产系统一直是企业级解决方案需要考虑的重要内容，而接口的处理是遗产系统融入企业级解决方案的关键所在。UML是一种面向对象的建模语言，但是它对接口、构件规格说明及构件建模概念支持甚少。该文通过对UML进行扩展，并且利用企业应用集成(EAI)中提供的应用编程接口(API)，提出一种将遗产系统构件化的方法。

Abstract: Legacy system is a major issue of the enterprise solution so far. Interface is the bridge between the solution and the legacy system. UML is an object-oriented modeling language, but it provides little support to interface, component specification and component modeling. This paper presents a method to componentize the legacy system by extending the UML and applying the API of EAI.
