摘要
本文简要讨论了软件需求定义及其语言的有关基本概念，重点介绍了图形化对象式需求定义语言ＮＤＯＲＬ的设计思想以及主要的语言结构与成分．该语言是一种以面向对象方法支持软件需求定义的半形式化语言，具有形象易读、表达力强和便于实现到形式功能规约的转换等特点。
This paper discusses some fundamental concepts of the software requirements definition, outlines the design rationale for a graphical object oriented requirements definition language NDORL which is a semi formal language that employs the object oriented method to support requirements definitions, and also introduces its main constructs in detail. The language is concise, very intuitive, and powerfully expressive. It is, moreover, easy to be transformed to a formal functional specification language automatically.
