Delicacy management of railway power supply and the density of trains increased made monitoring points increased and running changes intensify, a large number of fluctuation data need to be synchronized among different databases, but there are two problems need to be solved: (1) Existing various systems can not constitute an organic whole, information sharing across databases is difficult, integrated application is hard to begin; (2) Railway power supply management system is lack of data consistency and disaster tolerance capacity[4-6]. In order to solve these two problems, in this paper, Daffodil Replicator is a publish/subscribe message-oriented middleware that combined with database triggers to improve the reliability of the data synchronization ability, Daffodil Replicator can execute two-way synchronization between two databases which support Java Data Base Connectivity(JDBC), made data replication in different heterogeneous databases.
