Ontology Maps to Database: OntoMapDB approach

Ontology aims to organize knowledge of specific domain and provides a definition for the vocabularies and their relationships. Ontology plays an important role in the construction of database, it can be used to extend the classical model of databases. Several approaches were proposed to build database based on ontology structure. This Database called ’Ontology Based Data Base’ (OBDB) stores ontology and instances, which is more adaptable for computer application because it insures the interoperability between computer application and the OBDB. The OBDB approches presented in the literature has limits as focusing on specific type of ontology. In this paper, we propose a new approach of OBDB representation called ’Ontology Maps to DataBase (OntoMapDB)’. Our approach aims to manage information in database from ontology source, facilitate access to data for computer application and help developer in conceptual step. It consists on mapping ontology components as concepts, instances, and properties to database components as table, records, and attributes. OntoMapDB treats all types of ontology, canonical and non canonical ontology. It does not depend on a specific ontology model and it is relevant for each domain.
