SOLUTION: A distance calculating part 36 calculates a distance parameter indicating similarity of each donor sample of a donor side database, and each recipient sample of a recipient side database. A matching part 38 matches a donor sample with a recipient sample on the basis of the distance parameter. The matching part 38 carries out a distance order matching process of matching a donor sample with a recipient sample in an order of shorter distance while following a sample weight setting responding to a difference of the numbers of samples of both databases. The matching part 38 carries out an all donor application matching process of linking all donor samples to one recipient sample at a ratio responding to a distance between the one recipient sample and each of all donor samples.
