| 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.
本说明书实施例提供预计算模型生成方法、装置以及系统，其中所述预计算模型生成方法包括：根据用户查询的历史数据对应的至少两个查询维度，构建初始预计算模型；确定第一查询维度对应的维度基数，在所述第一查询维度对应的维度基数达到预设阈值的情况下，对所述初始预计算模型中的所述第一查询维度进行裁剪处理，得到目标预计算模型，其中，所述第一查询维度为所 |
