Abstract
An illustrative embodiment provides a computer-implemented process for semantic verification of multidimensional data sources that receives a trusted output from a trusted multidimensional expression engine, receives an un-trusted output from an un-trusted data source and determines whether a query produces a correct semantic result, wherein the correct semantic result is within a predetermined tolerance. Responsive to a determination that the query does not produce a semantically correct result, identifies queries having semantically incorrect results to form a local subset, notifies a query planner of semantically incorrect queries and determines whether to process queries locally. Responsive to a determination to not process queries locally, creates a set of simplified multidimensional expression queries for remote execution.
