More Information
Summary:The invention relates to a data query method and device, computer equipment, a storage medium and a computer program product. The method comprises the steps of obtaining a data query request for a multi-dimensional data space; the data query request carries a target dimension combination; acquiring a spatial index corresponding to the multi-dimensional data space; the multi-dimensional data space comprises a plurality of data subspaces, the spatial index comprises index bitmaps respectively corresponding to dimension members included in each dimension, each position in the index bitmaps respectively indicates one data subspace, and an element value of the same position in each index bitmap is used for indicating a subspace dimension combination corresponding to the corresponding data subspace; performing logical operation on the index bitmaps corresponding to the target members in the spatial index to obtain a result bitmap corresponding to the target dimension combination; and based on the result bitmap, det
