The system includes an intelligent query system. The intelligent query system includes a model configuration module, a data storage module, a calculation engine module, a rule engine module, a data export module, a file storage module, a page query module, a system management module and a system monitoring module. A multidimensional model is stored according to a time sequence, and data volume of computation can be effectively decreased with business processing logic not changed; and front-end page display can be realized by a text file, so that frequent operation on a database can be avoided, and the resource utilization condition of the database can be effectively reduced. Based on the improvement of the above two aspects, the performance of intelligent query is greatly enhanced, users can quickly obtain data, the problems of high communication costs in data acquisition, long cycle and slow response can be solved, requirements of business departments for intelligent data acquisition, work efficiency improvement and market response speed acceleration can be satisfied.
