  • Asynchronous replication of data changes by distributed update requests
    Patent number: 5261094
    Abstract: A method of replicating changes made to databases distributed throughout a computer network is described. A first program (TP1) in the Collector node instructs a second program (TP2) in the Collectee node to send all updates to a database since the last conversation. TP2 processes queries to retrieve any changes made since the last conversation between the Collector and Collectee nodes and send the data to TP1, which updates the copy of the database on its own system.
