A system and method for synchronizing data records between multiple database is provided. Each database includes data records that are modified to include at least one pair of synchronize parameters. In a two-database system including a first database and a second database, each data record is modified to include synchronization parameters for both the first and second databases. When an update is made to data record at one of the databases, an update message is transmitted to the other database including both synchronization parameters from the database where the update is made, along with the undated data record. An efficient master-slave configuration between the database then enables either database to resolve conflicts without further communications.
