Database Modelling Using WSML in the Specification of a Banking Application
نویسنده
چکیده
We demonstrate through a sample application, Ebanking, that the Web Service Modelling Language Ontology component can be used as a very powerful object-oriented database design language with logic capabilities. Its conceptual syntax allows the definition of class hierarchies, and logic syntax allows the definition of constraints in the database. Relations, which are available for modelling relations of three or more concepts, can be connected to logical expressions, allowing the implicit specification of database content. Using a reasoning tool, logic queries can also be made against the database in simulation mode. Keywords—Semantic web, ontology, E-banking, database, WSML, WSMO, E-R diagram.
