A method for data care in an offline distributed database network system (DBNS) comprising a central system (CS) with a central database (CD) and a plurality of node systems (NS) with local data bases (LD), whereby the local databases (LD) contain at least partially different subsets of data from the central database (CD), update data for the information stored in the databas es (CD, LD) of the database network system- (DBNS) is captured in a plurality o f node systems (NS), and the update information is transferred from the node systems to the central system or from the central system to the node systems - when an online link exists - in the form of replication objects which are structured into different types containing an identification key. When no online link is available, said replication objects are placed in an output line for transmission at a later point in time. |
