The invention includes a first process of inserting one row below each row of a column heading of an original table, inserting one column to the right of each column of a row heading, and entering a corresponding ID into each cell of the inserted row or column; a second process of inserting one row between the column heading and data portion, inserting one column between the row heading and data portion, and entering an ID of the dimension when inserted cells indicate a value of a dimension, entering no data when inserted cells indicate a measure, and entering an ID of a measure into a cell at the intersection of the inserted row and column when column headings and row headings indicate dimension's values; and a third process of identifying a dimension, value thereof, or measure corresponding to each cell of the data portion of the created template table.
