A data processing method and system including a plurality of databases linked by at least one communication channels, a synchronization set which defines the objects or records to be synchronized between the plurality of databases, and a synchronizer for each database which controls and monitors the synchronization between databases and accesses a local database to which the synchronizer is connected. Each synchronizer includes a communications module which monitors and controls the communication with other databases and at least one table synchronizer which controls and monitors the synchronization of the local database and access to the local database. Each table synchronizer includes a table synchronizer engine which handle the synchronization management for its table synchronizer, a plug-in which handle the generic database communication for its table synchronizer, and a driver which controls communication with the local database. The data processing method synchronizes data records of a source database and a destination database. The method includes defining a synchronization set for data records existing in the source database, synchronizing the source database and the destination database based on the synchronization set, and changing the definition of the synchronization set while synchronizing the source database and the destination database.
