The Analysis And Optimization Study Of The Algorithm For Mining Association Rules

Data Mining (DM) is a technique that aims to analyze and understand large amount of data and reveal knowledge hidden in the data. It has been viewed as an important evolution in information technology. During the past over decade, new concepts and techniques on data mining have been presented, and especially in the latest few years, some of them have been studied in higher levels.Data Mining uses the classification, association, sequence analysis, clustering analysis, machine self-study and other statistic approaches to find potential, unaware but useful information and knowledge from large database. It is a new subject that involves a lot of subjects and develops with these subjects. Data Mining system can find out lots of patterns, in which association rules that describe the interesting relations among the items in given data sets are the important area. The connection rule is used to express some kind of relationships between group of objects in database, it is first proposed by R.Agrawal etc.
