ABSTRACT:
A master-detail provider is provided for processing user requests for data stored in one or more data source. The master-detail provider has a query analyzer, a master-detail link handler, a master query handler and a detail query handler. The query analyzer analyzes one or more queries included in a user request, and determines any set of the queries in which the queries are linked by one or more master-detail links. The master-detail link handler relates the queries of each set that are linked by one or more master-detail links as a master query and one or more detail queries. The master query handler causes preparation of the master queries to generate master query plans, and generates provider queries by incorporating the master query plans with related detail queries and related master-detail links. The detail query handler handles the detail queries causing preparation of the detail queries to generate detail query plans.
