Abstract:
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 an
d 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.
