Examination is made of whether an array that matches an array (b), in which the values of the field "topology" of a table generated by converting XML data are arrayed in order of record number, is registered in a topology pattern table (a) included in the pattern data set, and when there is a registered entry, it is registered in individual compressed data (b), with the order of the registered entry as being TPNo. Similar processing is performed on a field "node name" also, and NNPNo is registered in individual compressed data. For other fields, the column of the field is registered in individual compressed data. Then, the individual compressed data are additionally registered in the individual compressed data set.
