Abstract
An information processing device reduces a time of processing for adding an attribute name performed in each node. The device memorizes its own segment. This segment is at least one segment among each segment made by dividing a range of a key into a plurality of segments, so as to make the segments neighbor with each other. The key is generated about at least two attribute names using an attribute name and an attribute value based on a specified order relation and is of size-comparable form. The device judges whether a key generated from an attribute name and an attribute value is included in its own segment or not.
