An obtaining unit obtains relational data containing relationships that can be converted into at least one graph. A determining unit determines whether to store certain graph data in the first or second memory, based on at least any of specification information specifying a storage destination for the certain graph data, or relations of connection with respect to the graph data stored in the first or second memory, and a data size of the relational data. A memory controller stores the certain graph data in the first or second memory based on the determination.
