面向对象系统设计方法研究

首先对面向对象系统设计方法的使用背景进行了分析，提出了此背景下面向对象系统设计的方法，并简单给出了实例。整个设计包括静态结构模型的设计和动态行为模型的设计，静态结构模型是通过一系列类和类层次的设计表示系统的静态组成结构，动态行为模型则是用类的实例化对象描述系统的行为过程。设计结果用一系列图形表示。整个设计过程是相互交替、补充的。此方法充分利用了面向对象的机制，如继承、封装等，体现了面向对象技术的特性，如扩充性、重用性等

Research on Object Oriented Systems Design Method

In this paper, the context of the object oriented systems design is analyzed first.Then the method of object oriented systems design based on the object oriented analysis model is proposed.The whole design model is composed of the system static structure model and the dynamic behavior model.Static structure model represents the system component and structure through the design of a series of classes and class hierarchies.While the dynamic behavior model describes the system behavioural course by using the operations of classes' instantiated objects.And the design results are represented by figures.With the full use of the object oriented paradigm, systems designed by using this method can reflect the characteristics of object oriented techniques, such as extendability, reusability, maintability, etc.
