Query: Modellieren mit Heraklit   Heraklit is an infrastructure for modelling large, computer-integrated
systems. We discuss the central requirements for such models (hierarchies, user
view, transfer of informal into formal ideas, schematic models, equal treatment
of digital and person-bound processes) and explain how Heraklit supports these
requirements. A case study shows the usability of Heraklit in practice.
