一种用例驱动的应用系统分析和设计方法

本文给出了一种用例驱动的系统分析和设计方法，其要点是：（1）在分析阶段，采用例驱动方法，从Model-View-Controllr(MVC)的角度理解用户需求，建立MVC分析模型；（2）通过分析当前主流MVC开发环境，抽象出Model和View两者之间交互的一般实现模式，据此抽象的实一细节对MVC分析模型进行细化，完成从MVC分析到MVC设计和实现的无锡过渡，本文最后还介绍了方法在实例“停车场信息管理系统”开发中的运用实践。

A USECASE DRIVEN APPROACH TO ANALYZING AND DESIGNING APPLICATIONS

An application be thought of as an outline map,including the abstract solution space of the problem domain(i.e. .user's requirement) and all the related concrete implementation space. An approach to the developing of this map is proposed in this article. We start with understanding and acquiring the user's requirement from the viewpoint of MVC paradigm at the analysis phase, and build the MVC analysis model by applying the usecase driven approach. The MVC analysis model is then refined by the elements of the abstract implementation environment which is generalized from the current MVC implementation environments, and gradually converted seamlessly into the MVC design/implementation model. Finally a complete process of exercising the approach to the developing of a practical mid- sized MVC application,called City Parking Lot Management System is presented.
