A Improved Algorithm Apriori

An information burst age is coming with the various application of Information technology. How to maximize the information is a very important problem for the decision-maker of the companies. Besides getting the regular information from the Database by SQL-query, people still need to mine the data relation which is unclear but really exists. Association rules is one of the data mining methods, the famous algorithm Apriori is a method, which can be used to solute those problems.This article analyzes and studies the improved algorithm Apriori based on the algorithm of mining association rules Apriori. The main idea is to decrease the number of candidate items and to decrease the times of Database scanning. The solution is available. It upgrades the speed of data mining and decreases computer's I/O operation. It's proved to be more efficient than the traditional method.
