Abstract
A database management systems is disclosed for solving distributed queries across a range of resources. In known systems, database retrieval from multiple sources suffers from problems of reconciliation of data between resources and resource or data incompatibility. The invention allows full database integration even in the case where a database includes a plurality of disparate database resources having differing ontologies (data structures). The system has an ontology server which is used to store the ontologies of various database resources and the query engine is designed to consult the server so that it can construct a query that will operate effectively across the disparate database resources.
