Abstract: As for the consistent decision table, this paper proposes a new method of data reduction. Compared with traditional data reduction method, this paper considers the relation between attribute reduction and attribute value reduction, that is, the method firstly gives attribute value reduction, and then conducts attribute reduction, last this paper proves it. However, lots of general method of data reduction, they dont consider the relation and much redundant operations.

Key words: data reduction, attribute reduction, relation, redundancy
