Ontology based synthesis of database schemes

The article discusses the problem of automatic synthesis of a relational database schema to store information about states of a subject area by using its description logic ontology. It presents an algorithm for explication and analysis of information about those relations between concepts, which are relevant to the problem. Example of generating of a database schema fragment is presented. The difference between the proposed algorithm and other ones, which are generating database schemes by using а description logic ontology, oriented to logical queries to database only, but not to usual SQL queries from usual engineer information systems, is outlined. Database schemes, which are generated by the algorithm, are sufficient to store any facts about a subject area which are consistent with description logic ontology, grants references constraints and effective access to data by means SQL queries.
