Model (business informatics)
In business informatics (BISE), models are primarily used to describe real and socio-technical systems . The descriptive means used for modeling are mainly borrowed from computer science, but are reinterpreted for their intended use in describing the real world in terms of their semantics : unlike the models in computer science, BISE models do not denote the formal system of software, but rather real-world operational or administrative processes , Objects, organizations and organizational units . Since the real world, unlike artificially created, formal systems, cannot be grasped without the subjective performance of the viewer ( ontic idealism), models of BISE are mostly not viewed as images (as in computer science), but as construction results.
The model elements are identified with terms from the respective technical language of the application context. Since, in addition to knowing the modeling language used ( formal aspect ), knowledge of the technical language ( natural language aspect ) is also necessary for interpreting the model , one often speaks of semiformal modeling languages and models in the context of business information systems .
In business informatics, the term model is used not only for the totality of the established system including the semantics, but also for the graphical representation of a specific situation using the defined model elements.
Further terms for BISE models are information model, organizational model or technical conceptual model.
