Abstract: When support and transaction database are changing，the problem of how to effectively update association rules is a hot topic in data mining research.However the problem of how to effectively update association rules after a change of the attributes in transaction database has not too much attention.ACA+ and ACA-algorithm do researches on signal attribute change of it.Based on this，the paper proposes incremental updating algorithms for mining association rules based on the change of multiple attributes，which are MACA+ and MACA-.By structuring transaction-attribute matrix，it can effectively solve the problem.

Key words: multiple attribute, data mining, association rules, multiple attribute change, incremental association rules updating
