Abstract: A system and a method are disclosed for automated generation, management and documentation of device assemblies by means of a data processing system, which has at least one data source for the supply of mass data and an entry module for creating and managing objects. The entry module interacts with a graphic module, which generates schemas from a combination of the created objects, and transfers the schemas generated by the graphic module into a processing module for the generation of one-to-one corresponding instances by means of a multiple allocation of the schemas to the mass data.
