MULTIDIMENSIONAL QUERY SIMPLIFICATION USING DATA ACCESS SERVICE HAVING LOCAL CALCULATION ENGINE

An enterprise business intelligence system includes a data access service that provides consistent availability of functionality for querying multidimensional data sources regardless of the capabilities of the underlying data sources. The data access service disassembles a multidimensional query into execution units, and may optimize the multidimensional query such that individual execution units may be executed locally or remotely to achieve increase computational efficiently.
