Abstract: In order to reduce the operational complexity of data synchronization in the China Railway Ticketing and Reservation System(TRS), enhance data synchronization performance and consistency, and improve the ability to meet complex business data needs during the data synchronization process, this paper designed a data synchronization platform for TRS, proposed a platform architecture and data synchronization process, and comprehensively utilized intelligent concurrent warehousing, data consistency detection, and streaming data transmission technology to improve the data service capability of the TRS. The platform has been tested in multiple business applications of the TRS with good application results.
