Abstract: Provided are a system and method for implementing an incremental data comparison. The system includes: a synchronization T environment, a simulation F environment, a simulation tool, a memory database, a comparison tool and a result database. The T environment includes a synchronization environment core application, a traditional commercial database, an incremental synchronization tool and a synchronization environment distributed database. The F environment includes a simulation environment core application and a simulation environment distributed database. The simulation tool is configured to play back a T environment service and an F environment service. The memory database is configured to store a mapping relationship between message values of the T and F environment. The comparison tool is configured to compare data in the T and F environment according to the mapping relationship between the message values. The result database is configured to store comparison result data generated by the comparison tool.

Abstract: A data processing method includes: after receiving an export request for exporting data from the distributed database, acquiring, by a database import and export management node an active transaction list and export table distribution information at a current moment; notifying, by the database import and export management node, a corresponding database that the corresponding database performs a data export operation according to the export table distribution information; after determining that the corresponding database completes the data export operation, sending, by the database import and export management node, the active transaction list to a database agent node of the corresponding database; and after receiving a data consistency reverse compensation statement returned by the database agent node, importing, by the database import and export management node, the data exported by the corresponding database into a predetermined database and instructing the predetermined database to execute the data consistency reverse compensation statement.
