With the development of the global information movement,the number of data people collect enlarges quickly while the information people got grows slowly.In order to excavate the information hidden in these data which is important for decision making,the reserch of data mining technology becomes an urgent need. In this article,we mainly discuss data mining technology and its use on Tax quota ratification system .It is devided into two parts,in the first part,we first introduce the basic knownledge of data mining and the technology it utilized,then we present an algorithm for data mining based on multi-objective optimization.In the second part,we introduce the development of Tax quota ratification system,which is based on this algorithm.The testing result of the system improved that the presented algorithm is validate. |
