Abstract
Each of a plurality of servers includes a shared information storage region for storing information to be shared with other servers. The servers operate so as to match data of the shared information storage regions with each other. A first server manages a first local database. A second server generates query information for accessing the first local database, and stores the query information in the shared information storage region of the second server. The first server acquires the query information from the shared information storage region of the first server, and stores the result with respect to the query information in the shared information storage region of the first server. The second server acquires the result from the shared information storage region of the second server.
