摘要:
An object is to integrate pieces of information related to mutually the same target, though the pieces of information do not contain, in common, an attribute unique to one target. To achieve the object, from a generated condition storage unit storing generated integration conditions each specifying one or more attributes contained, in duplicate, in pieces of information related to mutually the same target, one of the generated integration conditions specifying one or more attributes being the same as one or more attributes contained in integration target information is obtained as a generated integration condition corresponding to the integration target information. A CI 200b containing the attributes specified by the obtained generated integration condition and in which the values of the attributes specified are identical to the values of the attributes contained is determined as a CI related to the same target as the integration target information is related to.

An access control apparatus that controls access to an information management apparatus that stores configuration elements and relationship elements indicating relationships between the configuration elements, includes a storage unit that stores one or more predetermined configuration elements in association with user information that identifies a user and stores one or more combinations of a type of a configuration element and a type of a relationship element in association with the user information, as an access control rule set for each user, and a determining unit that determines that, when a combination of a type of a configuration element stored in the storage unit in association with user information and a type of a relationship element indicating a relationship between the configuration element and another configuration element is stored in the storage unit in association with the user information, the another configuration element is accessible.
摘要:
A virtual tape apparatus is interposed between a host and a tape device so as to store data transmitted from the host to a logical tape volume. The virtual tape apparatus includes: a data communication unit that receives data transmitted from the host; a RAID device having a logical tape volume for storing the data; a management table that manages attribute information of data stored in the physical tape volume; a position determination section that determines the write starting position of the data stored in the logical tape volume on the physical tape volume based on the management table; and a drive control unit that writes data in the logical tape volume to the physical tape volume based on a result of the determination.
