Uml-based Demand For Access To Technology

Requirement Engineering is indispensable to software project.and it is the key to software quality and reliability.UML (Unified Modeling Language) is an important application of Object-Oriented technology,and is also a useful analyzing and designing tool toward objects in modern Software Engineering.Firstly.strategies and technologies of capturing requirement are discussed in the paper and it is presented that Use Case model is a standard way to describe requirement in the course of developing software. Use Case technology are studied systematically. Use Case extend and description are studied mainly. Lastly.direction of future research are discussed...
