Financial institutions accumulate a large amount of data in their daily business. Except for the value they are used in the first time, the accumulated data is not useless. It also has endless "surplus value". It can be said that the one can master and rationally use the core resources of data, the one can further grow and develop in the next fierce competition
It is necessary to make effective quality management and deep mining of data in order to extract the intrinsic value contained in the data, let the data in the sleep give full play its value, and then provide financial institutions with decision-making basis in various fields such as marketing, risk management and customer management.
