<P>PROBLEM TO BE SOLVED: To efficiently improve throughput as the entire distributed type database system. <P>SOLUTION: Data of a distribution shared NID (DSN) related to correspondence of a key value which is an actual value and a key value identifier (NID) taking a unique value within a range of a data type that the key value has in the entire distributed type database is divided into respective data types and distributed and stored in each of a plurality of slave nodes. When distributing and storing the data of the DSN in each of a plurality of slave nodes 15, 17, and 19, one slave node to be a storage destination is determined from the plurality of slave nodes 15, 17, and 19 on the basis of the key value related to a registration request. <P>COPYRIGHT: (C)2012,JPO&INPIT |
