Summary: | The embodiment of the invention provides a pre-calculation model generation method, device and system, and the method comprises the steps: constructing an initial pre-calculation model according to at least two query dimensions corresponding to historical data queried by a user; a dimension base number corresponding to a first query dimension is determined, under the condition that the dimension base number corresponding to the first query dimension reaches a preset threshold value, the first query dimension in the initial pre-calculation model is cut, a target pre-calculation model is obtained, and the first query dimension is one of the at least two query dimensions. By reducing the size of the pre-calculation model, the calculation resources and the storage cost are reduced, and the time for scanning the pre-calculation result is shortened.
