基于UML的系统需求分析

OBJECT-ORIENTED REQUIREMENTS ANALYSIS BASED ON UML

UML(Unified Modelling Language)是面向对象方法建模的语言标准工具,在系统建模过程中应用很广泛,在UML技术指导下,针对软件开发过程中的需求分析阶段,提出了一种结构清晰的功能需求分析模型,在系统用例图的基础上,建立类图和时序图,从静态和动态不同侧面表达系统模型,迭代的建模过程保证了模型的一致性,一个实例详细描述了系统功能需求分析建模的过程。

UML is the standard modeling language of Object-Oriented method which has an abroad application in system modeling, A function requirements modeling is proposed based on the UML technology among the software requirement phase, class diagram and sequence diagram are created after finishing the use case diagram, which express the system through static and interaction aspects. The iterative process makes a consistency modeling, An example is depicted in detail.
