Abstract
A method for synchronizing a database server to a current status of a client database using data cache techniques is provided. Upon initiating synchronization, the database server receives an identification of a client connection, and creates a server-cache-table having a structure that is compatible with the client database. Database records from a corresponding client-cache-table are received through the client connection and inserted into the server-cache-table. The server-cache-table is merged into the database server. Similar cache-tables can be utilized to synchronize data from the database server to the client. Optionally, a parent-cache-table can be created on the server and populated with records associated with the identified client. Queries and other database operations during synchronization can be performed over the parent-cache-table to further optimize performance.
