Atomicity data are stored at a block on a hard disc. The block includes a determined block aggregation (P1) existing only on the hard disc, a next generation determined block aggregation (C1) that is converted to a determined block aggregation at predetermined timing, and an atomicity block aggregation (S3) that is made out for every user based on the determined block aggregation (C1). A user (A) carries out a desired data change, etc. for the atomicity block aggregation (S3) and, when the user finishes data processing, the user integrates a block aggregation to store data from an atomicity block aggregation (S4) to the determined block aggregation (C2) and stores the integrated block aggregation on the hard disc as a determined block aggregation (P3).
