浅谈软件开发的面向对象技术

传统的面向数据、过程的软件设计方法，把数据和过程作为相互独立的实体，忽略了数据和程序间的内在联系．这样，在软件开发中对于不同的数据格式作同样的处理，或对不同的数据格式作不同的处理，都必需开发不同的程序，软件可共用的成分很少．因此，要进一步提高软件质量及软件生产率比较困难．面向对象和设计方法与传统的设计方法有本质的区别，该方法不仅使人们摆脱了具体的数据格式和过程的束缚，而且利用它所提供的对象和类的技术，在创建和组合可再用的软件成分时灵活方便．笔者简要介绍了面向对象方法的特点，并讨论了面向对象方法对软件质量及软件生产率的影响．

On the Object oriented Technique for the Development of Software

Traditional data oriented and procedure oriented software design method takes the data and the procedure as independent objects,which ignores the internal relations between them.The different programs must thus be designed for the same processing to different data formats or for the different processings to the same data format,and the share property of software is poor.It is difficult to improve the software quality and productivity.The essential difference between object oriented method and traditional data oriented and procedure oriented method is in that the former makes programmers break away from the trammels of data format and procedure,and use the object and class that it supplies to conveniently combine the software compositions that can be reused.This paper introduces the distinguishing feature of object oriented method,then discusses its effects on improving software quality and productivity.
