基于Oracle触发器的数据实时同步的实现——在员工医疗保险系统中

The Implementation of Data Real-time Synchronous Replication Based on the Oracle Trigger——In the Customer Medical Insurance System

经济的全球化发展促使分布式应用系统对数据同步复制的要求越来越高。从数据同步的需求出发,着重论述了系统需求及触发器实时同步的工作原理,以及利用实例介绍了数据库数据双向实时同步的实现方法,最后给出了对性能的影响及后备方案。

The globalization of economic development makes the requirement of data real-time synchronous replication of distribution application system higher and higher.This article begins with the requirement of data synchronous replication,emphasizes the system requirement and the trigger theory of data real-time synchronous replication.It illustrates the implementation method of real-time synchronous replication of dual-direction data,the influence of system performance and the back up solution.
