A method, apparatus, and article of manufacture for computer-implemented use of object relational extensions for mining association rules. Data mining is performed by a computer to retrieve data from a data store stored on a data storage device coupled to the computer. A multi-column data store organized using a multi-column data model is received. One of the columns in the multi-column data store represents a transaction, and each of the remaining columns in the multi-column data store represents elements of that transaction. A combination operator is performed to obtain candidate itemsets of data from the multi-column data store, each itemset being a combination of a number of rows of the multi-column data store. Large itemsets of data are generated from the candidate itemsets, wherein each itemset has at least a minimum support. Association rules are generated from the large itemsets of data, wherein each association rule has at least a minimum confidence.
