Abstract
At least one of a first application program and a second application program sends an access request to a second cache management module, which receives the access request, and references the second cache management table to identify the storage location of the access-target data conforming to the access request. When access-target data exists in first cache area, the second cache management module sends a request to the first cache management module storing the access-target data, and where access-target data does not exist in the first cache area, acquires the access-target data from the second storage device. When the access-target data is in first cache area, the first cache management module acquires the access-target data conforming to the request from the relevant first cache area, and sends access-target data to the second cache management module.
