Abstract

See full text

A method, apparatus, and article of manufacture for replicating data stored in source database tables in a database management system implemented by a server at a remote client implemented on a client computer. The method comprises the steps of receiving a subscription message from the client computer, wherein the subscription message specifies a remote client database table and a data replication period, receiving a change log from the database management system at the data replication agent, generating a table of changed data by using the change log, data replication period, and source database table to reconstruct changes to the remote client database table, and transmitting the changed data table to the remote client.
