Patent number: 11983109Abstract: An air freight rate data caching method and system. The method includes converting air freight rate data into a data format of a first-level cache, and storing same in the first-level cache; performing, on the basis of a flight origin city and a flight destination city, data fragmentation on the air freight rate data stored in the first-level cache so as to generate fragmented data; and storing the fragmented data, after same is validated, in a second-level cache. Each data node of the fragmented data cached in the second-level cache only includes part of the air freight rate data on which a fragmentation algorithm can be performed, and therefore, the horizontal expansion capacity of a cache system is improved relative to the case where cached data copies are all complete sets.Type: GrantFiled: July 8, 2020Date of Patent: May 14, 2024Assignee: TravelSky Technology LimitedInventors: Jinfang Du, Lingbin Meng, Wen Wen, Chunsheng Ju, Bing Liu, Yongbo Fei
