Title: Method and system for transmitting messages for database
Inventor: BRIQUE OLIVIER
IPC: G06F17/30
Filed: 2000-09-06
Abstract: When updating databases distributed over a subscriber network, a management centre sends messages addressed to each of said bases. When a large number of databases need to be addressed, the time for accessing each of them increases considerably in view of the fact that the information has to be repeated to ensure that the messages have been properly received. The invention concerns a method which consists in transmitting criteria wherein a certain number of databases will identify themselves and in updating said bases instead of addressing each database individually.
