摘要： An obtaining unit obtains a first-type request which includes address information corresponding to a writing instruction or a reading instruction with respect to a value. A converting unit converts the first-type request into a second-type request which includes a key having a combination of the address information and version information. The version information is updated every time the writing instruction is issued with the position indicated by the address information as the writing position. Based on the second-type request, a control unit either performs a writing operation for writing the value corresponding to the key in a key value store type database including a plurality of storage devices each of which is set either as a master storage device or as a slave storage device, or performs a reading operation for reading the value corresponding to the key from the database.
