Abstract: According to the traditional data mining methods have been calculated with high time complexity, time-consuming problem, proposed massive data mining method based on fuzzy association rules, based on fuzzy theory, association rules mining, mining fuzzy association rules analysis, implementation of fuzzy association rules is discussed, on the basis of this, the mass data are fuzzy with the establishment of fuzzy database, and to classify the aggregation of fuzzy data in fuzzy database, and discretization of continuous attributes, determine the frequent association rules in fuzzy database, so as to realize the data mining method based on Fuzzy Association rules. Experimental results show that the method proposed in this paper can reduce the time and memory consumed by data mining, and this method has more support for data mining, and puts forward new ideas for data mining.
