Data synchronization method and system for heterogeneous data source

The invention discloses a data synchronization method and system for a heterogeneous data source. The method comprises the following steps: receiving a data synchronization request, and obtaining a source database type, a target database type, synchronization data attribute information and task scheduling configuration information of the data synchronization request; reading a corresponding template file according to the source database type and the target database type, assembling the synchronous data attribute information based on the template file, and generating a corresponding data synchronization task according to the task scheduling configuration information; and generating a data reading thread and a data writing thread corresponding to the data synchronization task according to the task scheduling configuration information, extracting to-be-synchronized data from a source database, and writing the to-be-synchronized data into a target database. Through configuration in the data synchronization reques
