The current work has arisen with respect to the growing importance of ontology modelling in Information Systems development. Due to emerging technologies of Semantic Web, it is desirable to use for this purpose the Web Ontology Language OWL. From the other side, the relational database technology has ensured the best facilities for storing, updating and manipulating the information of problem domain. This work covers analysis of the process how ontology of a particular domain described in OWL may be transformed and stored in a relational database. The algorithms for transformation of domain ontology, described in OWL, to relational database are proposed. According this algorithm, ontology classes are mapped to relational tables, properties to relations and attributes, and constraints – to metadata. The proposed algorithm is capable to transform all OWL Lite and part of OWL DL syntax. The further expansion of the algorithm to cover more capabilities of OWL should be based on the same principles. The prototypical tool, performing transformations, has been implemented as add-in for the ontology development tool “Protégé����. The methodology of transformation is illustrated with an example.
