One of the well-studied problems in data mining is the search for association rules. The task of association rule mining is to find certain association relationships among a set of data items in a database. Given a user defined minimum support and minimum confidence threshold, association rule mining is to find all the rules having at least minimum support and minimum confidence. There are three primary quality measures for association rule, support and confidence and lift. In this paper we present the relation between the measure of association and the criteria of association rule for ordinal database.
