PROBLEM TO BE SOLVED: To provide a master file difference automatic output device capable of performing difference extraction even if layout change (item addition, item deletion) is performed in a master file to be compared.SOLUTION: Record unit difference output software 20 refers to master configuration comparison table file 12 in which the relationship between items in a new master file and items in an old master file is previously defined, extracts the difference in record unit between the old master 10 and new master 11, and outputs a record unit difference file 30 to a storage device 2. Then, master file difference detailed output software 21 uses a common-part (mismatch) file (old) 33 and a common-part (mismatch) file (new) 34 in the record unit difference file 30 to compare item values of each item in each record with each other, and displays only the item whose item value is updated. |
