摘　　要：为了简化异构数据库的访问,提高上层应用程序的复用性和系统的可扩展性,本文介绍一种基于插件动态库的异构数据库访问方法。该方法通过公用中间动态库向应用程序提供动态访问数据库的统一接口,屏蔽数据库的类型差异,使得应用程序和异构数据库之间具有相互独立性,从而有效地解决电力实时监控系统中异构数据库透明高效的访问问题。该方法已在实际系统中得到了有效应用。In order to simpify the access to the heterogeneous database and improve the reusability of upper applications and system scalability,this paper presents a heterogeneous database access method based on dynamic library plug-ins.The method provides unified interfaces for the applications＇ dynamic access to database,shielding the discrepancy between different databases.It makes mutual independence between applications and heterogeneous database,and effectively solves the problems about efficient access to the heterogeneous database among the power real-time monitoring system.The method has been effectively applied in the actual system.
