Software Requirement Modeling Research Based on Use Case

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.
