WIPO Patent Application WO/2012/115194

Kind Code:

A1

Abstract:

A distributed data base system that distributes and stores distributed shared NID (DSN) data to a plurality of slave nodes, separated into data type, said data relating to the correspondence between a key value that is an actual value and a key value identifier (NID) that takes any value within a range for the data types for key values within a whole distributed data base. When distributing and storing the DSN data to the plurality of slave nodes (15, 17, 19), the storage destination slave node is determined from among the plurality of slave nodes (15, 17, 19) on the basis of the key value relating to the registration request.
