Integration concepts like Data Warehouse set the goal to improve analysis a nd availability of information in Management Support Systems (MSS). In thes e concepts the different data structures and data flows resulting from vari ous application systems have to be considered. Therefore suitable modeling approaches are necessary for both describing different data as well as meet ing the changeable requests of MSS. In this paper we present an uniform dat a structure for analytical data. The resulting Unimu Schema has been used i n a MSS at an energy supply company.
