一种基于结构化分析的面向对象设计方法

一引言结构化分析/结构化设计(SA/SD)是一种成熟且广泛使用的软件分析设计方法,目前存在大量用这种方法开发的系统.SA/SD以功能分解为指导思想,分析设计的结果适合用结构化程序设计语言来实现.SA/SD中最重要的文档是数据流图(DFD)和数据字典(DD)

This paper discussed a new object-oriented design method SOD,which has been applied to the development of a real system. Based on the result of structured analysis (Data Flow Diagram and Data Dictionary),SOD outputs an object model which facilitates the implementation using object-oriented programming. SOD's concepts,steps and output documents is presented systematically together with an example in this paper.
