摘要： 针对传统瀑布型开发模式的缺陷,八十年代出现了新型的需求分析技术——快速成型法。本文介绍一个软件工具系统RAPID,它支持快速成型法,可用于数据处理系统开发过程中的需求分析和规格说明阶段。RAPID结合了“结构化分析”(SA)、“实体联系法”(ER)和“用户软件工程”(USE)等多种软件开发技术,能辅助软件人员描述需求并快速建立目标系统的原型。本文叙述RAPID系统的目的、所使用的方法及其总体结构。还介绍它的两个子系统PAPID/UI和RAPID/FN。

Abstract: A new technique- 'RAPID prototyping' is advocated in 1980's to solve the problems of the traditional waterfall model. This paper describes a software toolbox called RAPID, which supports the development of data processing systems in requirement analysis and specification phase. RAPID combines Structured Analysis, Entity. Relationship Approach and User Software Engineering; and assists software engineers in specifying requirements and rapidly creating prototypes. The paper presents the goal, the underlying methodology and the architecture of RAPID, and then outlines its two subsystems: RAPID/UI and RAPID/FN.
