摘　　要：针对电力监控系统移植、扩展和升级困难的现状 ,提出了基于COM技术的数据库设计方法 ,利用COM技术的语言无关性等优点解决上述问题。该方法通过设计数据驱动、表格管理和数据访问等组件模块完成对系统数据库的连接、读写和更新等数据库访问功能 ,并按组件功能采用层次结构管理所有组件模块 ,用户通过更新组件模块的方式扩展和升级系统。采用该方法开发的电力监控系统在兼容性、可扩展性等方面优势明显 ,在“ER2 0 0 0电力监控系统”中的应用验证了该方法的可行性和实用性。According to the difficult condition in the transplant, expansion and upgrade of power monitoring system, a database design method based COM is proposed, in which the advantages of COM are used, such as computer language independency. COM modules of data driving, table management and data access are designed to implement the database access functions of system database connection, data accessing and refreshing. The modules are organized to different layers by functions and the system can be expanded and upgraded by reorganizing relevant modules. The power monitoring system developed with this method has obvious advantages in compatibility and expansibility, and the feasibility and practicability are proven by its application in 'ER2000 power monitoring system'.
