基于应用层数据模式的电量计费系统的研究和开发

分析了电量计费系统的数据访问的特点 ,设计并实现了一种基于应用层数据模式的数据访问机制 ,简化了应用程序的数据访问逻辑并真正实现了应用程序与底层数据的逻辑独立 ,提高了系统的现场适应性和可扩展性。同时在此基础上完成了基于商用数据库的用户自定义的数据统计模块和用户可定制的报表生成工具 ,方便了用户对系统数据的分析。该系统已经在鞍山电业局投入运行。

The research and development of tele-metering system based on application layer data mode

This paper analyzes the property of data access of TMS and a data access mechanism based on application layer data mode is designed and realized,which simplifies the application data access logic and the logic independent between application and database is then realized and the adaptability and expansibility is improved.Based on the mechanism,a user defined statistics module and a user designable report create tool are completed,which make it easy to analyze the data for the user.The system is already in run in Anshan electric bureau.
