Abstract

The goal of the paper is to present a method based on reversible, information preserving transformations and transformation algorithms between OWL 2 ontology and relational database (OWL2ToRDB). The authors propose the hybrid approach, when a part of ontology constructs is directly represented by relational database structures and another part having no direct correspondences in a relational database is stored in metadata tables. Experimental investigation of the implemented OWL2ToRDB tool has shown that the created method is capable for lossless transformations and obtained database schemas are practically and flexibly usable in information systems. When a number of ontology instances is growing, the proposed method shows better query performance time in comparison with traditional methods when all instances are processed in computer memory. Ill. 7, bibl. 15, tabl. 1 (in English; abstracts in English and Lithuanian).
