A computer-readable medium storing therein a data conversion program that causes a computer to execute a process that includes receiving after a schema of a database has been changed from a former schema to a new schema, a processing request concerning the database; judging based on difference information concerning the former schema and the new schema, whether in the processing request, a condition that specifies process data subject to processing, has been changed by the new schema; searching the database for conversion data whose format is to be converted from the former schema to the new schema, the searching based on judgment results obtained at the judging and on the processing request; and converting the format of the retrieved conversion data, from the former schema to the new schema.
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.

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.
