ABSTRACT:
Atomic data are stored in blocks on a hard disk. The blocks are grouped into a committed block aggregate P1, which exists only on the hard disk, a next-generation committed block aggregate C1, which is converted into a committed block aggregate at predetermined times, and an atomic block aggregate S3, which is created for every user based on the committed block aggregate C1. User A makes desired data changes to S3. When user A terminates the data processing, the block aggregate storing the data is merged, like from the atomic block aggregate S4to committed block aggregate C2, and stored on the hard disk as a committed block aggregate P3.
