PROBLEM TO BE SOLVED : To select a synonymous column candidate for a column of a first data model easily and properly from a second data model.
SOLUTION : A CPU 101 of a data integration server 10 detects first rare words that the number of words present as a word related to a configuration of a table other than the own table of a factory data model 210 is equal to or less than a prescribed number while detecting second rare words that the number of words present as a word related to a configuration of a table other than the own table of a common data model 140 is equal to or less than a prescribed number, determines whether a second column included in the common data model 140 satisfies a determination condition for determination to be a synonymous column candidate of a first column of the factory data model 210, and if the determination condition is satisfied, selects the second column as the synonymous column candidate of the first column. The determination condition includes a condition where one of the first rare words around the first column matches one of the second rare words around the second column.
