METHOD FOR COMBINING DISTRIBUTED DATA BASES

摘要

In a first step, the databases (DBV1,DBV2) are extracted from the components (V1,V2) of a data processing system. In a second step, the extracted databases are merged in a new database (DBVneu) outside the data processing system, while data that are no longer valid are erased, and valid data are incorporated without change. In a third step, the new database is supplemented by any changes (LOGV1, LOGV2) to the databases made during the processing in the second step.
