ABSTRACT:
An automatic aggregation method for automatically aggregating a plurality of records using a computer, the plurality of records each including a plurality of items including a key parameter and a numerical value which is at least related to the key parameter, includes the steps of (a) inputting one of the plurality of records to the computer; (b) adding at least one node, representing contents of the input record, to a position, corresponding to the key parameter included in the input record, of a hierarchical tree; (c) updating a value of the at least one node added to the hierarchical tree and a value of a node on a level higher than that of the at least one node, in accordance with the numerical value included in the input record; and (d) repeating steps (a) through (c) until all the plurality of records are processed, thereby outputting an aggregation result for each of items of the key parameter.
