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.
