Abstract—clustering a group of data based on the relatedcomponents and its similarity, using fuzzy association rulemining is a key to implement data mining in Soft Computing.Traditional way of clustering is only one object is assigned to acluster, when it is overlapped and had more cluster to an existingobject then fuzzy logic is used. Here Modification in the criteriavalue for membership value of clustering point of an object.Proximity measure is applied in Box metric equation. Ananalysis is made on retail database this makes better enhancingway to predict the sale and performance based on associationrule mining using fuzzy model. The category has been selected indifferent number of products grouping the products based onthe need from customer and Integration of Apriori Model tomulti membership and multiple support approach for saleperformance prediction.Index Terms: Fuzzy Logic, Clustering, Rule Mining, Apriori,Retail Database.
