A method of maintaining synchronization among multiple databases is provided. The method includes the steps of receiving a data update request for a data record at a database, and comparing a timestamp of the data record to a timestamp of the data update request. The data in the data record is updated with the data update request if the timestamp of the data update request is substantially greater than the timestamp of the data record. Otherwise, the data in the data record is updated with the data update request if the operational priority of the data update request is higher than the operational priority of the data record. Alternatively, the data in the data record is updated with the data update request if the node priority of the data update request is higher than the node priority of the data record.
