  • Data storage system and data storage program for atomic transactions
    Patent number: 8055853
    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 S4 to committed block aggregate C2, and stored on the hard disk as a committed block aggregate P3.
