Abstract: In a data management system of a machine learning model, flag management information (a flag importance management table) manages and defines respective flags corresponding to, of a plurality of processes included in the life cycle, one or more predetermined processes. An operation unit assigns flags defined in the flag management information to input data and output data of the model in accordance with involvement in the predetermined processes when the model is operated. A data management unit determines, with respect to each of the input data and the output data, the necessity of storage of data on the basis of a flag assigned to the data by the operation unit.
