Synchronising a set of records in a first database with a second database which comprises a copy of the set of records. The first database has a transaction log with entries indicating changes made to records in the first database, the second database stores a global version. The system can be used for resynchronising the second database with the first database by updating the global version to give an updated global version, copying all records in the set of records from the first database to the second database and associating the updated global version with each record copied to the second database. The system then continues to process entries in the transaction log relating to the set of records to record changes from the first database in the second database and associates the updated global version with any changed records in the second database during copying all records in the set of records. |
