PROBLEM TO BE SOLVED: To provide a technology capable of relatively quickly acquiring a search result even in the case of searching large amounts of RDF data.SOLUTION: A plurality of query node parts N03 acquire RDF data corresponding to a graph pattern allocated to a query node part N03 from a database. Then, the query node part N03 transmits the acquired RDF data to a join node part N02 at its parent position. The join node part N02 connects the RDF data transmitted from a query node part N04 being the child of the join node part N02. |
