The present application discloses a method and related device for storing freight rate data. After obtaining the target freight rate data and the release time of the target freight rate data, if the logical primary key of the target freight rate data is not stored in the database, a new addition operation is performed on the target freight rate data to construct a data structure corresponding to the logical primary key. The target freight rate data is stored in a data block included in the data structure, so that the corresponding freight rate data can be retrieved from the data block during subsequent search. The starting version identifier of the target freight rate data is determined based on the release time, a target corresponding relationship between the starting version identifier and the storage position of the target freight rate data in the data block is established, and the starting version identifier and the target corresponding relationship are stored in a hierarchical block. Therefore, compared to searching in all stored freight rate data, searching based on the logical primary key and the starting version identifier narrows the search scope, improves query efficiency, and thus shortens the calculation time and improves user experience.
