The invention discloses a multi-dimensional analysis method for multi-level storage data. The multi-dimensional analysis method comprises the following steps: step 1, building a unified data model; step 2, building a multi-dimensional analysis model; step 3, performing multi-dimensional analytic calculation and demonstration: a calculation engine automatically generates an aggregate calculating sentence, corresponding to a next-level calculation node, of the multi-dimensional analysis model according to routing information, a calculation agent executes aggregation operation to generate a pre-aggregation result and uploads the pre-aggregation result onto a main-control server, and then secondary aggregation calculation is executed to generate a multi-dimensional calculation result set; the calculation engine forms a dimension member inquiry algorithm according to the multi-dimensional analysis model and the unified data model, inquires a dimension member, generates cell objects of a demonstration report and fills the multi-dimensional analysis result into the cell objects to realize multi-dimensional demonstration of the multi-dimensional analysis result. The multi-dimensional analysis method can realize real-time multi-dimensional analysis of hierarchical storage data without centralizing data in advance.
