To solve the problem that the existing algorithms of mining association rules result in a number of rules, upper closed set of an item set and generalized association rule base were defined. And some important propositions were obtained , e. g. the upper closed set of an item set exists uniquely and is the item set . From these propositions , the generalized association rule base of a transaction database was proposed. It contains the information of all the association rules in the database and the rules have a uniform structure. As a result , the number of rules can be reduced as many as possible. In addition , a mining algorithm for generalized association rule bases was proposed and its validation was proven using an example.
