用面向对象方法构造用电管理信息系统

Based on Object-Oriented Method to Developing Management Information System for Power Supply

以Ｃｏａｄ－Ｙｏｕｒｄｏｎ ５层次方法为基础，吸取Ｒｕｍｂａｕｇｈ动态建模的思路来认识、理解和描述用电管理过程并构造模型。采用向向对象分析和设计的方法，利用现有大型网络关系型数据库管理系统（ＲＤＢＭＳ）和前端开发工具Ｐｏｗｅｒ－Ｂｕｉｌｄｅｒ ６．５，开发了供电企业用电管理信息系统。在基类的基础上，作者自定义了一些类，使类具有继承性的特点，并使用电管理信息系统具有可重用性，易修改和扩充，具有广阔的应用前景。

Based on the Coad-Yourdon's Five-Organized method and adopting the idea of Rumbaugh Dynamic modeling, the management process of electric power supply is described and a model is established. With the OOA (Object-Oriented Analysis) and OOD (Object-Oriented Design) methods, using large scale network RDBMS and Power Builder 6.5, an electric power supply management information system is developed. Some classes are defined which have the characteristics of inheriting. At the same time, it makes the system have the characteristics of easy amending and extending.
