DATA DELETION DETERMINATION PROGRAM, DATA DELETION DETERMINATION METHOD, AND DATA DELETION DETERMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To enable deletion of accumulated data, with effects of deletion suppressed, in a data process which is constituted by a plurality of processes, and in which the output result of a process is used in other processes.SOLUTION: The above objective is achieved by a data deletion determination program which causes a computer to execute the processes of: referring, for each of a plurality of pieces of output data generated in the course of finding a final result through a plurality of processes from object data and accumulated in a storage device, to the processing contents of each of the plurality of processes and information on the output data accumulated in the storage device, and generating deletion effect information that indicates the degree of effects due to deletion of the output data, using an execution time taken in one or more processes until the output data is generated; and extracting output data to be deleted from the storage device, on the basis of the deletion effect information of each of the plurality of output data.SELECTED DRAWING: Figure 3
