COMPUTER READABLE STORAGE MEDIUM HAVING DATA PROCESSING PROGRAM RECORDED THEREON AND DATA PROCESSING APPARATUS

A data processing program generates a layered list structure which is a data structure formed of a plurality of layers. The layered list structure includes a data element layer which includes a plurality of data elements, each including a substance of predetermined data or information indicating a position on a memory storing the substance of the predetermined data, and is a layer in which the data elements are included as a linked list; and a relay node layer positioned above the data element layer and including a plurality of relay nodes, each associated with one element in a layer immediately below. The relay node layer is further divided into layers; in each relay node layer, the relay nodes are ordered in accordance with the order of the elements in the layer immediately below, and in each relay node layer, the relay nodes ordered adjacent to each other are associated together.
