The invention provides a synchronization device for source data and target data and a database synchronization method and system. Through monitoring source tables in source database, the source unique index of the source data in the source table based on the operation of the data manipulation language is added to the intermediate table corresponding to the source table; after satisfying the synchronization conditions, relevant source data to be synchronized in the source table is searched based on the source unique index recorded in the intermediate table and a synchronization message carrying the source unique index is sent to a target in the target library corresponding to the source table; searching and synchronization are carried out in the target table according to the synchronization message. The synchronization process does not need to be done in archive mode, which guarantees the performance of database and saves disk space.
