摘要
针对电力EAM(enterprise asset management)系统数据库分布各地且结构各异引起的数据不一致性问题,采取在电力EAM系统的数据访问层设计一个数据库中间件的方法。通过数据库中间件对各种数据库中数据进行格式转换和语义翻译,实现上层应用程序对异地异构数据库的透明访问。在广西象州电力EAM系统中使用了该数据库中间件,该中间件将各数据库系统无缝集成并解决了数据不一致性问题。
To solve the problem of data inconsistency caused by the distributed databases and the different structure of databases existing in electric power EAM （enterprise asset management） system, the method of desiring a database middleware in the data access layer of electric power EAM system is adopted. Different kinds of data formats are converted by this database middleware, the upper layer applications can access the remote databases with different structure transparently. This database middleware has been used in Guangxi Xiang Zhou electric power EAM system. Finally the ability of database middleware to integrate databases seamlessly and to solve the data inconsistency problem is demonstrated.
