The data transformation platform is designed in accordance with modularization, which masks the access from upper application by data wrapping module and submits DataSet objects to upper application. DataSet exchange module finishes heterogeneous data exchange by using XML capsulation of DataSet. For the synchronization process of heterogeneous data, it uses table trigger and Updates Information Table to capture change from source database table. The Update Information Table keeps the DML statements operated on tables which need to be synchronized. In the course of synchronization, synchronization module extracts DML operation field from Regenerate Information Table DataSet. At last, it updates the table fields of destination database by using command object.
