Research and Case Analysis of Apriori Algorithm Based on Mining Frequent Item-Sets

In the background of the information age, importance data resources can be imagined, and use means—data mining has also emerged. current situation, all industries are in a relatively equal stage, should make good resources, Apriori algorithm to mine association rules, formulate marketing strategies, promote sales growth and slow down loss national GDP. Countries also to make predictions support decisions. Briefly describe basic concepts of data rules. Only with understanding data mining rules we better understand algorithm, why it is one most classic influential algorithms. Understanding its essence function, suggesting suggestions for improvement by analyzing the ideas algorithm, its process, advantages and disadvantages, through collected from supermarket Bozhou City, Anhui Province, China; application the field e-commerce universities, effect will achieve.
