Abstract
A database synchronization system (10) is disclosed that synchronizes the content of a central database stored on a central computer (16) with one or more remote databases stored on one or more remote computers (18). A data extract and transfer application (20) is provided on each of the remote computers (18). A migrator application (26) processes the audit trail files (24) of the remote computer (18) to create a database of change (28). When the database of change (28) reaches a size threshold, the data extract and transfer application (20) shuts down the migrator application(26), processes the database of change (28), and restarts the migrator application (26) to begin the creation of another database of change. The data and information in the database of change are converted into a series of flat files (48) that are transferred over a communications line (14) from each of the remote computers (18) to the central computer (16).
