送电管理信息系统中的数据库设计

Database design in power transmission management information system

管理信息系统的数据库设计是其组建的核心问题 ,为保证运行系统的安全、可靠、实用性 ,介绍了送电管理信息系统的功能及内容 ,针对该系统的特点和要求 ,提出了基于UML的需求分析方法和采用PowerDesigner设计工具进行数据库设计 ,阐述了系统数据库的结构特点 ,即C/S/S与B/S/S 3层结构相结合。实践证明 ,这些设计方法有效保证了系统的顺利运行。

The database design is the core during the establishment of a management information system.To ensuring the safety,reliability and practicability of system operation,its functions and contents are introduced.Regarding to its features and requirements,the demand analysis method based on UML is applied and the Power Designer design tools are adopted for database design.The structural features of system database,i.e. the combination of C/S/S and B/S/S are explained.All of these design methods that ensure the proper system operation are proven by practice.
