Patent ID: 7788224

Claim:
A method for updating a remote data base with sets of data of a master data base, the method comprising: forwarding said sets of data from the master data base to an intermediate data base; and forwarding said sets of data from the intermediate data base to the remote data base, wherein the intermediate data base and the remote data base are coupled by a synchronization protocol, wherein said synchronization 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 data base system controlled by a data base management, wherein the master data base stores additional sets of data not stored in the intermediate data base, wherein the master data base stores said sets of data according to a first data model, and the intermediate data base stores said sets of data according to a second data model, wherein an object update of the master data base and the intermediate data base is executed within a single transaction in which a single commit is executed over the master data base and the intermediate data base, wherein the master data base and the intermediate data base each comprise logically independent sections, and wherein the logically independent sections comprise at least one of a first section storing a fixed number telephone portability information, a second section storing a local number portability type information, and a third section storing a geographical number portability type information, and a fourth section storing a mobile number portability type information.
