<P>PROBLEM TO BE SOLVED: To enable coupling processing of sum set integration processing and equivalent linking processing for carrying out the sum set integration processing and equivalent linking processing in combination without sorting categories in a link result table for storing record of sum set in a target database system. <P>SOLUTION: When carrying out coupling processing ((X or Y) and Z) of sum set integration processing (X or Y) and equivalent linking processing (A and Z), appropriate items in (X and Z) and (Y and Z) are sorted and collected using reference flags in Z-table. Sum set (OR) of the flags is calculated, and an order is given based on the reference of Z-table. By collecting data based on the order, the data are stored in the link result table without sorting the data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
