基于用例模型的面向对象需求分析

Requirements Analysis of Object-oriented Based on Use Case Model

面向对象方法正在逐渐取代传统的方法,日益成为当今软件工程领域的主流方法。在系统需求设计方法中用例模型已成为获取系统需求的主要技术,通过用例模型的建立和对用例的分析软件开发者可以准确地了解用户需求和系统功能。它是用户和软件开发者一起剖析系统需求的关键一步,可以推动需求分析后各阶段的开发工作。

The Object-oriented methods is gradually replacing the traditional methods. It is increasingly becoming a mainstream of today＇s software engineering methods. Use case model has become the main technique to capture requirements in the system design approach. Through the use case model and the analysis of use case, software developers can accurately understand the users＇ needs and system functionality. It is the key step for users and software developers in system requirements analysis, paving the way for later various stages of development.
