Multi-dimensional analysis method and system for multi-level storage data

The invention relates to the technical field of business intelligent data, in particular to a multi-dimensional analysis method and system for multi-level storage data, and aims at solving the problem that in the multi-dimensional analysis method, regularly acquired data cannot be acquired in advance. Storing a query record of a user, receiving a query request of the user, judging whether the query record the same as the query request exists in the data query log or not, calculating a time difference value of obtaining data information through the query request each time according to the number of repetition times of the repetition record, and obtaining a query interval; and judging whether data information corresponding to the query request needs to be acquired in advance according to the number of repetitions and the query interval, if the data information needs to be acquired in advance, performing pre-acquisition according to the target index and the target dimension to obtain pre-information, and updatin
