Mapping Heterogenous Ontologies through Object Views.
Kazimierz Subieta · 2000
The traditional concept of a database view is currently under influence on new ideas, in particular the CORBA approach to distributed objects, objectoriented databases, XML and other Web technologies, semistructured data, and autonomous mobile agents. These new trends cause widening the scope of database views by novel features, which are beyond the current theoretical and conceptual paradigms of database systems. New concepts related to database views are wrappers, adaptors, mediators and ontologies. The paper discusses features of object-oriented views, which have to fulfill new needs and expectations. The discussion is focused on integrating heterogeneous databases into a federated database. Emphasis is put on relaxing the database view concept from limitations induced by stereotypes inherited from the relational data model, to fulfill nowadays requirements concerning efficient integrating heterogeneous data sources and services.
