Latest Patents

Wei Tang holds a patent titled "Caching methods and a system for entropy-based cardinality estimation." This patent involves a system where query conditions are received in a cache from a query optimizer of a Database Management System (DBMS). Dynamic statistics for the query conditions are maintained in the cache. Actual statistics are received in the cache after the query conditions are executed in the DBMS. The system provides entropy-based estimated selectivity values for executing the query conditions, which assist the query optimizer in developing an effective query plan. These estimated selectivity values are based, at least in part, on the dynamic statistics and the actual statistics.
