Research on the key technologies of coal production statistical system based on the decision tree

According to production statistic work for coal enterprise developing present situation and actual application situation in our country now , the production statistic system for coal enterprise, based the C/S and B/S unify composite structure model, has been proposed in this paper.The system use the exploitation method of combining SAD and Object Oriented. It has realized many essential functions, such as the technical specification dynamic management, the integrated information intelligence analysis, the report form continual calculation and the printing, the data balancing and so on. In addition, decision tree algorithm of data mining technology is introduced in the system to establish a mine effective decision-making model, which realizes the evaluation of the mine effectiveness.
