UML与SDL结合使用的研究

Research on Using UML with SDL

1引言 在介绍如何将SDL与UML结合在一起使用之前,让我们先来回顾一下UML和SDL各自的适应范围.它们性能上的差异在于它们在工程应用中的不同的阶段.UML的非形式化的自然特性使其成为一种性能优越的建模语言,它应用完全的面向对象的分析(OOA)方法.然而对于实施,UML却不能胜任,通常要用传统的程序设计语言如C++/Java来完成,而SDL的形式化定义使得它取代传统的程序设计语言有了可能.

In this paper we investigate how Unified Modeling Language(UML)can be used together with the Specification and Description Language (SDL) standardized by International Telecommunication Union (ITU). In our research, it is discovered that a SDL user can benefit from UML,similarly,a UML user is able to take advantage of the SDL- Especially for a real-time system development, UML should be utilized in analysis of the requirement, and SDL should be used in system design.
