Abstract
A database is stored in a plurality of pages that are a plurality of logical storage areas constituting a logical storage space. Data writing to a database in the logical storage space is performed in a page unit. A storage control apparatus coupled to an external storage and including a cache device writes data to the cache device in a page unit. The storage control apparatus determines whether an execution condition on external writing that is writing to the external storage is satisfied. When a result of the determination is true, the storage control apparatus writes data stored in the cache device to the external storage in a bulk unit that is larger than a page unit and is a writing unit in which consistency is maintained.
