  • a) performing a group-by query on the transaction table to generate a set of frequent 1-itemsets;

    b) determining frequent 2-itemsets from the frequent 1-itemsets and the transaction table;

    c) generating a candidate set of (n+2)-itemsets from the frequent (n+1)-itemsets, where n=1;

    d) determining frequent (n+2)-itemsets from the candidate set of (n+2)-itemsets and the transaction table using a query operation;

    e) repeating steps (c) and (d) with n=n+1 until the candidate set is empty; and

    f) generating rules from the union of the determined frequent itemsets.
