摘要: Techniques for accessing a parallel database system via an external program using vertical and/or horizontal partitioning are provided. An to management (DBMS) configures mappers process specific portion of query results on access module processors the DBMS that house results. The is submitted by and directed organize in or manner. Each mapper accesses its processing designated AMP set AMPS
