Method and system for managing view

摘要

Information to define a view (134) for simplifying relational operations in a database (132) is distributed to individual local database management systems (131) in a corresponding computer (136) handling queries. Upon a query on the view (134) from the application program (138) running in the computer (136) said query request is processed in the computer (136) to comprise a request to process within the view 134 defined as the set of base tables (133-1) ,..., (133-n). Thus, each database management system (131) conducts relational operations on the requested view (134) contained within the database (132), in conformity with said processing request.
