基于“用例”的软件需求建模方法研究

The Research of the Software Requirement Modeling Based Use Case

应用软件工程的基本思想、方法和原理,结合统一建模语言在面向对象分析与设计中的应用,对应用"用例"方法建立软件需求模型进行分析和研究.提出了应用"用例"建立软件需求模型过程中,必须用活动图集成"用例"之后,才能准确描述"用例"之间关系,从而完成应用"用例"进行软件需求模型的建立、完成需求分析目标的观点.

In this paper, under the guideline of the theory, methods and thinking about software engineering, and application of UML in OOA＆D, the history, importance, methods and the relations of software requirement modeling based on use case were researched. Then, how to describe the relations of the use cases？ Under the condition of the activity diagram drawn and with the help of the activity diagram, the relations of use cases were expressed clearly in case diagram.
