Information System, Method and Program for Managing the Same, Method and Program for Processing Data, and Data Structure

摘要

An information system includes a plurality of data storage servers that manage a data constellation in a distributed manner, an ID assigning unit (112) that assigns logical identifiers to the plurality of data storage servers on a logical identifier space, a range determination unit (114) that correlates a distribution of data in the data constellation with the logical identifier space so as to determine a range of values of the data corresponding to the logical identifier, and a destination resolving unit (340) that obtains, when searching for the destination of a node which stores any data having any attribute value or any attribute range, a logical identifier corresponding to a range of an attribute value space of the data which matches at least a part of the attribute value or the attribute range, on the basis of a correspondence relation among the range of values of the data, the logical identifier, and the destination address, with respect to each of the data storage servers, and determines the destination address of the data storage server corresponding to the logical identifier as a destination.

1. An information system comprising:
a plurality of nodes that manage a data constellation in a distributed manner, the plurality of nodes respectively having destination addresses being identifiable on a network; an identifier assigning unit that assigns logical identifiers to the plurality of nodes on a logical identifier space; a range determination unit that correlates a distribution of data in the data constellation with the logical identifier space so as to determine a range of values of the data corresponding to the logical identifier of each of the nodes; and a destination determination unit that obtains, when searching for a destination of a node which stores any data having any attribute value or any attribute range, a logical identifier corresponding to a range of the data which matches at least a part of the attribute value or the attribute range, on the basis of a correspondence relation among the range of values of the data, the logical identifier, and the destination address, with respect to each of the nodes, and determines the destination address of the node corresponding to the logical identifier as a destination.
