Foundations and principles of Conceptual Modeling
The basic notions of the NEMO summer school include the terms of enterprise modeling, modeling methods, etc. We start with some general observations about those notions and their role in (business) informatics. The second part of this contribution is dedicated to foundations of conceptual modeling. Here we pose the question of what the very basics of (discrete) models are, and how a systematic setting of modeling techniques, in particular for enterprise models, may be achieved. A business process is usually composed of workflow. A reasonable workflow is sound: a sound workflow can always reach its terminal state, and upon termination, no “garbage” remains. We present methods to adequately model and analyze workflows, in particular a most liberal composition operator for workflows that preserves soundness (i.e. composition of two sound workflows is a sound workflow again). This allows to stay in the world of sound workflows during the construction of large workflows and business processes.
