GLOBAL DATABASE MANAGEMENT SYSTEM INTEGRATING HETEROGENEOUS DATA SOURCES |
摘要 |
A database management system 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 a complex query analysis system that is arranged to find and link all database resources having the required elements for a specific database query. This then enables the query to be processed more efficiently .
