  • Patent number: 7831618
    Abstract: A database management system is provided for protecting data from being malicious update or deleted. The system is arranged to hold as a table attribute an insert-only attribute and a row deletion prohibition period, and as an access right attribute a row insertion date and time holding column name and to specify a row insertion date and time when a row was inserted, for disabling said date and time data. When requesting a table data update or a row deletion, the table attribute and the row insertion date and time are checked for preventing the malicious update and deletion.

  • Patent number: 7194575
    Abstract: A disk volume access controlling method includes the steps of setting a threshold number of times of accesses from a computer to a predetermined disk volume per time unit, acquiring a number of times of accesses to the predetermined disk volume per time unit, seeking whether or not the number of times of accesses acquired exceeds the threshold number of times, creating a mirror volume for the predetermined disk volume in case that the number of times of accesses acquired exceeds the threshold number of times, and changing an access pass between the computer and the predetermined disk volume to another access pass between the computer and the newly created mirror volume. It then becomes possible to distribute accesses to a certain disk volume, and further to make the accesses to a plurality of volumes even.
