ABSTRACT:
To provide a database which has plural log storage areas, and eliminates the sort in the restoration process by means of the application of logs, thereby carrying out the restoration quickly. A management server allocates DB servers to a corresponding one of plural data storage areas so as to access the corresponding one. The DB servers store data to the allocated data storage areas. When the data is referenced or updated, a log representing a data change history is stored in preset log areas for each data server. When the management server transmits a notification to change the data storage areas, area remapping logs are stored in log areas.
