摘要： Data of distributed shared NID (DSN) related to a correspondence relationship between a key value to be an actual value and a key value identifier (NID) taking a unique value within a range of a data type possessed by the key value in a whole distributed database is classified every data type and is distributed and stored in each of slave nodes. When the data of the DSN is to be distributed and stored in each of slave nodes 15, 17 and 19, one of the slave nodes which serves as a storage location is determined from the slave nodes 15, 17 and 19 based on a key value related to a registration request.
摘要翻译：分配共享NID（DSN）的数据与作为实际值的键值与键值标识符（NID）之间的对应关系相关，在整个分布式中具有键值所拥有的数据类型的范围内的唯一值数据库对每个数据类型进行分类，并分布存储在每个从属节点中。当DSN的数据要被分发并存储在从节点15,17和19中的每一个中时，作为存储位置的从节点中的一个从从节点15,17和19基于密钥值来确定与注册请求相关。

摘要： Data of a distributed, compressed and restored index (D-CRX) related to a correspondence relation between a key value related to a registration request and NID, and data of a distributed and compressed result set cache (D-CRS) related to a correspondence relation between a distributed row identifier (RID) taking a unique value every column in a table constituting a distributed database and the NID are distributed and stored in each of slave nodes 15, 17 and 19. When the data of the D-CRX is to be distributed and stored in each of the slave nodes 15, 17 and 19, the same slave node as the slave node determined as a storage location for the data of the D-CRS is determined as a storage location of the data of the D-CRX in relation to the data of the D-CRX to which the same NID as the NID indicated by the data of the D-CRS is assigned.
摘要翻译：与与注册请求相关的密钥值与NID之间的对应关系相关的分布式，压缩和恢复的索引（D-CRX）的数据以及与对应关系相关的分布式和压缩结果集缓存（D-CRS）的数据在构成分布式数据库的表格中的每一列采用唯一值的分布式行标识符（RID）和NID之间的关系被分发并存储在每个从节点15,17和19中。当D-CRX的数据为被分配并存储在每个从节点15,17和19中，与作为D-CRS的数据的存储位置确定的从节点相同的从节点被确定为D-CRS的数据的存储位置，分配与由D-CRS的数据指示的与NID相同的NID的D-CRX的数据的CRX。
