Abstract:
A computer-based method applied at a central application platform for analyzing data from one or more on line analytical processing data sources, the method comprising the steps of:a) receiving from an end-user a query for retrieving data from an on line analytical processing data source; b) dividing said query into a plurality of partial queries; c) designating each of said partial queries as a simple partial query or a complex partial query as appropriate, a simple partial query being defined as one that can be processed by said on line analytical processing data source and a complex partial query being defined as one that cannot be processed by said on line analytical processing data source; d) sending one or more of said simple partial queries to said on line analytical processing data source for evaluation, and receiving a response from said on line analytical processing data source; e) evaluating said complex partial queries by emulation methods to produce results; f) combining the results of said evaluations of said complex partial queries with said responses from said on line analytical processing data sources to generate combined results; and g) presenting said combined results to an end-user.
