ABSTRACT:
A database synchronizer facilitates computing systems which have client-side and server-side applications that share data in similar database structures, but which do not maintain a continuous connection to a single shared data source. In general, a database synchronizer is used to share data among many nodes on the computing system. The database synchronizer is used to synchronize the data in a central database for a particular client with the data on that client's intermittently-connected computer. Updates performed by either client or server are propagated to the other side when a connection is established and eventually from the server to other clients in the system.
