PROBLEM TO BE SOLVED: To provide a technique capable of shortening processing time in sorting of data. SOLUTION: Data values of a data row (11) as a sorting object are divided by grouping according to a group definition (10), and data rows (21 to 23) as group units are created. Each group is created by optionally dividing the whole range of object data with an appropriate number (size), and is divided in the order of a forming value. The whole rows (24 to 26) are combined with each other in the group order after individually sorting the data rows (21 to 23) as group units. Thus, a data row (12) as a sorting result is acquired.
