Abstract
A data query method is provided. A data query request for a target data model is obtained. Based on the data query request and target metadata corresponding to the target data model, a target physical table corresponding to the data query request is determined from a plurality of physical tables corresponding to the target data model. The target metadata is determined based on the plurality of physical tables. The plurality of physical tables includes a basic table and a pre-aggregated table. The basic table is configured to record basic data of one granularity, and the pre-aggregated table is configured to record data of a plurality of granularities. Target query data corresponding to the data query request is obtained based on the data query request and the target physical table.
