基于用例的软件需求建模研究

Software Requirement Modeling Research Based on Use Case

需求建模和用例技术是软件需求工程研究的热点,文中旨在通过讨论二者的作用及相互关系,得到如何使用用例分析技术为捕获的软件需求建立简洁明了的逻辑模型的一般方法。文章首先介绍了用例、软件需求、需求建模等基本概念,然后探讨了软件需求建模的一般过程,最后结合实际案例给出了使用用例进行需求建模的实现方法。整个过程侧重于需求的获取、用例分析和建模的实现,并提供了一个简单的用于描述软件需求的用例规约。

Software requirement modeling and use case technology are hotpoints of research to the software engineering.The primary goal of this paper is to describe a general approach of software requirement modeling based on use case through a typical discussing of their feature and relationship.The paper first introduces concepts of use case, software requirement and requirement modeling.It then discusses a common process of software requirement modeling.Last,it gives an example to explain how to build a software requirement modeling based on use case.The whole process focus on software requirement capture,use case analysis and model building,and provides a use case specification of software requirement.
