Abstract: The invention relates to updating a data base that is jointly used by two or more different processing mechanisms on the basis of multi-dimensional data sets. A network component performing this task includes a master data base storing static data and a multi-dimensional generic data template having predefined data fields relating to elementary information determined by data input requirements of the different processing mechanisms. An interface receives accounting-related data sets from a plurality of individual sub-systems. Processing resources having access to the master data base generate for each accounting-related data set one or more associated multi-dimensional data sets by deriving elementary information included in the accounting-related data set and in static data associated with the accounting-related data set and by writing the derived elementary information in corresponding data fields of the data template.
