In order to deal with the frequently updating of data in practice, association rules incremental updating algorithm combining with time judgment begun to be widely studied. DingHu gave an association rule difference degree judgment method based on the completely frequent itemsets. This method can fully express the changes of association rules before and after the dataset updating, and reduce the times of the updating of association rules, therefore, this method was widely used. However, this method is not very accurate when calculating the new frequent itemsets. DFUP algorithm is proposed in this paper, and this algorithm solves the problem of the above algorithm by introducing a dynamic database.

Keywords: association rule, incremental updating, time judgment, association rule difference degree
