异构数据库复制技术的研究与实现

Research and implementation of heterogeneous database replication technology

在传统同构数据库复制技术基础上,针对现有方案大多依赖于特定DBMS,提出一种新型的异构数据库复制方法.该方法采用通用的数据库接口和数据结构,实现了与DBMS无关的特性.在数据库集群系统中,应用该方法进行节点之间的数据复制,可显著提高集群系统的可用性和可扩展性.

Data need to be replicated because of performance and availability in the cluster system composed of heterogeneous database,and data replication between different databases is an important issue to be solved.A new method for the heterogeneous data replication is described on the basis of the database replication technology.Since most of the existing solutions are dependent on the specific DBMS,a new fully heterogeneous data replication method is proposed and it uses common database interface and data structure to achieve the DBMS independence.Application of the method to the database cluster for data replication between backend data nodes improves the availability and scalability of the system.
