System for the transformation of a number of source databases having n legacy data models to a target database having one target model, for the purpose of providing corporate information, such as customer information with integrated customer images. Use is made of a merge database, having an intermediate data structure with which the source database is coupled to the target database. The merge database has a number of structure elements on which four basic operations are performed, namely PROJECTING: filling the table of the merge database from the source database, GROUPING: determining the target-object-id of the object to which the record belongs, RELATING: determining the targetobject-id of a related datum within the merge database, and CALCULATING: evaluation of an attribute of one table of the merge database. In this regard, the structure elements are read and changed by one of said basic operations according to a given processing matrix.
