The Technology Of Data Mining With Its Application On The System Of Information Of Computer-saling

With the coming of information age,more and more people realize the importance of information.Useful information hidden in plenty of data needs mining energently.The technology of Data Mining arises and develops unders such circumstance.The main tast of Data Mining is to extract or mine the useful information from the data.We can get great amount of data from the computer transaction every day.The data is very useful for us to make decisions on management.The paper concludes and introduces association rule about its concept,sort,model and step for mining the data,measure and some basic algorithm on the basis of the at research.At the same time,we analyse hopfield-network'smodel,character,energy-function,movement-equation and so on.Moreover,to the requirement of the system of information of computer -saling,we have done the following and there are good result.Fisrt,considering the weight and constraint,we propose the algorithm for the weighted and constraint association rule.Now,there are quite research findings on both the algorithm for weighted association rule and the algorithm for constraint association rule,but there is few algorithm for weighted and constraint association rule.We propose the algorithm for the system of information of computer-saling to think about the different payoff for different fittings of computer and to get only the information that we are interested in.The algorithm is useful for the later management of the saling-computer.Secondly,for the increasing of data,we propose an algorithm for incremental updating weighted association rule.We can get amount of data every day from the transaction of computer.We would come across the problem to how to get rules from the new-generating data.So we propose the algorithm for increment updating weighted association rule which has higher efficiency. Lastly,we design the system of auto-fixing the computer according to model of hopfield-network. This system has achieved not only in the requirements of thecustomers,but also the speed of the fixing process.
