PROBLEM TO BE SOLVED: To easily handle indefinite data by receiving the designation of registering as indefinite data and executing processing for defining the contents of data made indefinite based on information concerning the data. SOLUTION: This device is provided with a means for receiving the designation of registering as indefinite data, a means for holding information on data designated to be indefinite and a means for define-processing data contents made indefinite based on the information. Indefinite data revision information 4-2 houses information on some data when the updating person of the data desires to hold it and information on data to which another user protests when the user protects (not acknowledge) at the time of updating. An indefinite data processing part 8-4 processes based on indefinite data revision information 4-2. The register of indefinite data and the retrieval of not acknowledging user, etc., with respect to information 4-2 are executed by a database information detecting part 3.
