The plurality of object data items are respectively characterized by a data coordinate and identified by a data identifier. The plurality of data storage nodes are respectively assigned a node coordinate in a space identical to that of the data coordinate. After selecting as first data storage nodes from among the plurality of data storage nodes a plurality of data storage nodes each assigned a node coordinate having a relatively short distance from a data coordinate characterizing each of the plurality of object data items, any of the object data item is respectively stored in a data storage node determined based on a data identifier that identifies the object data item from among the plurality of first data storage nodes.
