Deductive enterprise model (DEM): a better approach to enterprise modeling. – E. E. Williams, P. C. Bassey and B. O. Akinkunmi
This work is centered on the deductive enterprise model (DEM) as a better approach to enterprise modeling and integration of any information system that will be able to deduce answers to questions that one would normally assume can be answered if one has a commonsense understanding of the enterprise. Review of other models is given and the generic enterprise model (GEM) is viewed as a subset of the DEM. Setbacks around these models are also discussed. Concepts about the educational (academic) system are defined and expressed using the First Order Logic (FOL) as representational language that can represent the deductive capabilities in the enterprise of concern. Deductive rules about these concepts were also expressed as axioms using the first order logic and they add up to the knowledge base as the inference mechanism when further implemented using PROLOG programming language. Instances from sample ontology of the academic system were used to further demonstrate the dynamic nature of the deductive enterprise model. Deductions made from these rules become updates to the knowledge base as deductions drawn become new facts and are added to the database of facts.
