Summary:The hit rate of when the application using a plurality of classes of data whose generation times are close to each other is not sufficiently high currently. A data management device of the present invention includes: utilization status storage means for storing a combination of a plurality of data classes used by an application; combination creation means for extracting, from data storage means storing data which is given one of the data classes, a combination of the data in which a difference of generation times between the data in the combination is within a prescribed time interval, from the combination of the data given respective ones of the data classes stored in the utilization status storage means; and discard determination means for determining, from the data stored in the data storage means, data other than those belonging to the extracted the combination to be candidates of deletion.
