Research on Engineering Cost Data Management System Based on Decision Tree Algorithm

The informatization level of the engineering cost industry in China is still relatively low and the development degree is unbalanced. After China acceded to the WTO, some foreign cost consulting and related enterprises began to enter China's ' s engineering cost market, and some large domestic enterprises also began to actively explore the international market. Under such a situation, we need to take the research on big data as an opportunity to drive the industry through data and establish and develop a highly autonomous big data industry chain through the government's ' s organization and enterprises' ' participation, aiming to achieve leapfrog development.
