Data processing method in tree form and data processing device

A data processing method reversibly processing data information input to a data processing device by a processing unit comprising:

• a data volume reducing unit reducing a data volume of the data information;
• and
• a developing unit reconstructing data information reduced in the data volume reducing unit, wherein:
• the processing unit is structured by overlaying processing layers formed of a plurality of cells;
• the data volume reducing unit performs unit processing on each of the plurality of cells having the data information;
• and
• the unit processing performs identification processing by a weight according to equivalence and distance of data from a cell group adjacent to the cells, reduces the cells by each of the processing layers in an order from a lower layer to an upper layer of the processing layers until a data position existing on a time axis of the cells stops to thereby reduces the data volume, and processes the data in a record analyze control unit.
