First Claim
1. A method for updating a remote data base with sets of data of a master data base system, wherein said sets of data are forwarded to an intermediate data base, said intermediate data base and the remote data base system being coupled by means of a synchronisation protocol, said protocol ensuring, that the remote data base is reliably updated, wherein said master data base and said intermediate data base are logically independent data bases each part of a unique data base system controlled by a unique data base management.

Abstract
The invention relates to a method for updating a remote data base with sets of data of a master data base system. The sets of data are forwarded to an intermediate data base, and the intermediate data base and the remote data base system are coupled by means of a synchronisation protocol. The protocol ensures, that the remote data base is reliably updated, wherein said master data base and said intermediate data base are logically independent data bases each part of a unique data base system controlled by a unique data base management, and also to master data base system therefore.
