<p>When a database of a database memory (122, 142) of a server (12, 14) is updated by a distributed data processing process performed by clients (20, 22, 24, 26, 30, 32) on an object to be controlled, a replication trigger generator (132, 152) generates a replication trigger. Based on the replication trigger, an updating information transfer unit (130, 150) transfers updating information to another server (12, 14). A database updating processor (128, 148) of the server (12, 14) which has received the updating information updates the database stored in the database memory (122, 142). <IMAGE></p> |
