摘要
面向对象(Object Oriented,简称OO)技术,源于对现实世界中自然结构的认识,充分体现了概括、分类和抽象的思想。本文就如何在3GL软件开发中引入OO的思想,提出了函数实体和消息变量的概念,分别对应于OO技术中的对象和消息的概念,并结合实例,分析了在3GL软件开发中引入OO思想的几个要点。
Put forward via an understanding of natural structures in real world, the Object Oriented Technology (OOT) reflects the principle of generalization classification and abstraction. About how to utilize OOT to de velop 3GL software, this paper proposes two concepts: 'Function Entity' and 'Message Variable' and each of them corresponds to object and message in OOT. Also, this paper presents an instance to illustrate major points of this utilization.
