Abstract
A database management system according to an embodiment includes a first node and a plurality of second nodes. The first node receives a query for requesting data from a client terminal and transmits the received query to any one of a plurality of second nodes in accordance with conditions. The plurality of second nodes acquire data by performing processing based on the query received from the first node and transmit the acquired data to the first node. The first node holds range information indicating a range of data held in each of the second nodes and does not transmit the query to the second nodes when the range of data to be retrieved for the query is not a range indicated by the range information.
