A conceptual modeling technique based on semantically complete model, its applications

Abstract

The article proposes a conceptual modeling technique based on Semantically Complete model, the main property of which is that relations carry complete information about interconnection of underlying object types. The paper describes consequences of this property; the most important one is the possibility to use a model relation without its proper name. The author introduces Semantically Complete Query Language, expressions of which is formulated without relation names, describes a closure mechanism allowing to request an interconnection of indirectly related object types by means of a simple enumeration of them. The technique is applied to conceptual modeling of a metallurgical enterprise Manufacturing Execution System as an example. The article proposes use of Semantically Complete model as a unified data access interface to distributed data stored in systems of different architectures and placements, introduces a conception of Semantic Browser based on this interface. The browser permits to view and modify data, has an embedded mechanism of semantic navigation between points of view on information, and a mechanism of creation and publication of new view points by users.
