SYSTEM AND METHOD FOR DIVIDING DATA

PROBLEM TO BE SOLVED: To improve the efficiency of data processing by logically dividing large amounts of data into capacities suitable for processing on the basis of an appropriate criterion. SOLUTION: Pre-connection data having a plurality of parameters are stored in a pre-connection data temporary storage part 12 as blocks bk for each datum having the value of the same division in the parameters, and the blocks bk whose values of only selection parameters are different are connected by a data connection part 14 as connection candidate blocks, and connection object blocks are extracted from the selected connection candidate blocks by the data connection part 14 so that the total of the capacities of the pre-connection data included in the blocks bk can exceed a prescribed capacity, and the extracted connection candidate blocks are connected, so that a connection file is generated, and written in a connection file storage part 20 by a data writing part 15.
