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.

数据转换平台的实现采用模块化设计，通过数据包装模块屏蔽上层应用对数据库的访问和将包装好的数据集对象提交给上层应用来实现，数据转换模块利用DataSet对XML的封装完成底层异构数据的交换；在异构数据同步的处理上，采用触发器结合更新信息表的方式获取源数据库上表内容的变化，更新信息表保存作用在同步表上的DML语句，然后在同步的过程中利用数据转换平台的同步模块对更新信息数据集中的DML操作字段进行数据抽取，最后通过命令对象将变化更新到目的数据库的表字段中。
