Database synchronization techniques are used for various application areas. Of particular, in the environments such as company Merger and Acquisition(M&A), business tie-up or change of working patterns, the requirement to synchronize data between heterogeneous databases become increase. In order to synchronize heterogeneous databases, we have to detect the data change occurring databases. In this paper, we implement a heterogeneous database synchronization system. For this, we collect the redo-log records which are stored when data changes are arisen in a database and restore them to SQL statements. We devise a mediator which transmits data among synchronization entries to synchronize heterogeneous databases efficiently, and it allows us to build a fault tolerant system occurring in database synchronization. |
