It is Time to propose a Complete Methodology for Designing Semantic Databases
Résumé
Nowadays, domain ontologies have been advocated by advanced applications. This phenomenon contributes to the generation of big semantic data hard to manage by the main memory solutions. Persistent solutions were proposed as an alternative to ensure the scalability of those applications. As a consequence, a new type of database is born, called semantic database (SDB). Several types of SDB have been proposed including different architectures of the target DBMS and storage models for ontology and its instances. By exploring the literature, we figure out that most important research studies were concentrated on the physical design of the SDB, where solutions were proposed to increase the performance of the final SDB. In this paper, we propose a design methodology dedicated to SDB including the main phases of the lifecycle of the database development: conceptual, logical and physical. The conceptual design of SDB can be easily performed by exploiting the similarities between ontologies and conceptual models. The logical design phase is performed thanks to the incorporation of dependencies between concepts and properties of the ontologies. Finally, a prototype implementing our design approach on Oracle 11g is outlined.
