PROBLEM TO BE SOLVED: To prevent a phenomenon such as throwback of data for efficient management of a master data while reducing an operation maintenance cost, in an information system in which a plurality of processes related to change application of the master data occur in parallel such as a workflow system.SOLUTION: Upon receiving an application data, the application data and a master registration data are compared with each other for values in unit of data item, and a data item that is a difference is provided with a flag, which is stored in a memory as a first differential data. Another data being processed that has been applied and the master registration data are compared with each other for values in unit of data item, and the data item that is a difference is provided with a flag, which is stored in the memory as a second differential data. Flags are examined in unit of data item for the first differential data and the second differential data stored in the memory, to determine validity of an application data. |
