Method and system for precisely enquiring GDS flight caching data

Abstract

The present invention provides a method and system for accurately enquiring GDS flight information, wherein the method comprises: receiving the flight enquiry condition; judging whether a matching enquiry condition is existed in the local cache or not, if yes, executing the next step; otherwise enquiring the GDS server, judging whether the time interval of the enquiry at this time and the enquiryat last time is shorter than the preset reference time or not according to the enquiry condition, if yes, executing the next step, if not, enquiring the GDS server; judging whether the present changerate of the ordering seat quantities is smaller than the reference change rate, if yes, enquiring the local cache, if not, enquiring the GDS server; increasing or updating the flight cache data basedon the enquiry result of the GDS server. According to the method provided by the invention, the flight information enquired from the local cache is more close to the flight information of the GDS server, the accuracy for enquiring the flight information from the local cache can be improved.

Description

technical field [0001] The invention relates to the technical field of communication of the global distribution system GDS, in particular to a method and system for accurately querying GDS flight buffer data. Background technique [0002] GDS (Global Distribution System), or "Global Distribution System", is a large-scale sales network system supported by a large-scale computer information service system that is applied to civil air transportation and the entire tourism industry. GDS provides a global product data platform. By adopting voluntary harmonized standards, trading partners can continuously coordinate product data attributes in the supply chain, share master data, that is, share data on GDS servers, and ensure data in each database. Synchronization and coordination between databases. Through GDS, travel sales agencies all over the world can obtain a large amount of travel-related information from airlines, hotels, car rental companies and travel companies in a time...

Problems solved by technology

[0004] However, the prior art method of using reference time to determine whether flight data is expired has the following defects: because the change of GDS flight data is not regular and linear according to time Yes, the method of distinguishing whether the flight data and the server data are consistent in time alone is not enough to keep the cached flight data and GDS data highly consistent, because the cached data is sometimes seriously distorted

In addition, because the flight data needs to be retrieved from the server for each unit of reference time, the number of visits to the server is relatively large, so the number of data transmissions between the server and the client is relatively large, resulting in a large amount of computation for the GDS system
