摘要
A data index establishment method obtains M raw data segments and a first-layer mapping relationship through segment fitting on raw data in a raw data table, and further obtains N first key segments and a second-layer mapping relationship through segment fitting on a first key of each raw data segment. In a subsequent data query process, a multi-layer mapping relationship is input from a to-be-queried key sequentially in descending order, until a location of the to-be-queried key in the raw data table is located.
