PROBLEM TO BE SOLVED: To prevent the meaning of a character string of input data from being lost by numerical conversion by making a display part display the input data itself even after the input data is converted into a numeral in a database. SOLUTION: When the input data is data having only elements of a character string, the input data is stored in the database as the character string itself and displayed at the display part. When the input data includes elements of a numeral, the data is displayed at the display part in the form of the character string before numeric conversion and the data having been converted into a numeral is stored in the database while mutually linked with it.
