对“销售点终端系统”进行面向对象建模

Object-Oriented Modeling for Sale Post System

面向对象的分析和设计方法是当前软件工程学的主流方法。其核心思想是利用面向对象的概念和方法为软件需求建立模型,完成系统设计。以“销售点终端系统”的设计为例,可以很好地说明如何将面向对象理论应用于开发实践系统。

The object-oriented analyzing and designing means is the main trend of current software engineering. The key to it is establishing model for the need of software by making use of object-oriented concept and means to accomplish system design. Taking the design of Sale Post System for example can domestrate clearly how to apply the object-oriented theory to practice.
