The SDL Library: Querying a Relational Database with an Ontology, Rules and the Jess Engine

In this demo we present the Semantic Data Library (SDL) which is used to query a relational database at a concept (ontological) level. The SDL integrates a rule engine, a relational database and a set of rules obtained from the transformation of an OWL ontology. This combination allows querying and inferring with data stored in a relational database using concepts, roles and rules. We propose an implementation of the method of querying relational database with extended rules and the transformation of OWL ontologies into sets of rules. Our demonstration is based on the previously presented financial crime ‘minimal model’ ontology and artificially generated data sets. Prospects of the future development of the SDL tool are presented.
