Latest Patents

Conrad Tang holds a patent for a method titled "Cost-based semi-join rewrite." This invention involves a method, apparatus, and computer program product for executing a relational database management system (RDBMS) in a computer system. The RDBMS manages a relational database comprised of one or more tables storing data. The system executes a query with a semi-join operation that includes an inclusion join and/or an exclusion join performed against at least an outer table and an inner table. The inclusion join returns a row from the outer table when there is a match with a row in the inner table, while the exclusion join returns a row from the outer table when there is no match with a row in the inner table. The RDBMS performs a rewrite of the query to avoid spooling and/or sorting of the inner table when the inner table is larger than the outer table, provided that the cost after the rewrite is lower than before the rewrite. This patent showcases his innovative thinking and problem-solving skills in database management.
