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.
