Abstract
Systems and methods that eliminate non-qualifying data for queries against data warehouses and improve execution time, via a dynamic filter component(s). In general, such dynamic filter components are derived from data during processing of the query and without being explicitly defined by the users within a query forwarded to the data warehouse. Moreover, an evaluation component can monitor efficiency of filter components (e.g., number of rows that can be eliminated), and dynamically change and/or update the evaluation order of such filters.
