Data mining refers to extracting knowledge from huge amount of data. Apriori algorithm is the paradigmatic algorithm of association rule, which enumerates all of the frequent item sets. When this algorithm encounters dense but noisy data, large number of extensible patterns emerge and hence, the algorithm’s performance diminishes dramatically. In order to find more worth rules. this paper explains the radicals of Association Rule Mining (ARM)and moreover acquire a general framework. This paper proposes selection of best attributes from the best rules obtained with Apriori algorithm. After that truly explore their influences and carry forward several run time demonstrations using a classification technique Iterative Dichotomiser (ID3). The research describes algorithmic discussion and comparison of the performance of classification algorithm with and without best attributes.
