There is still a little information. See if you can use it.
Research on Database in Railway Ticket Sale and Reservation System
Main contents:
1) Railway ticket selling and booking system (hereinafter referred to as the ticket system) is a key topic in the Ninth Five-Year Plan, and 1999 was listed as a "top priority" scientific research project by the State Science and Technology Commission.
2) The content discussed in this paper is an important part of the ticket system. The main contents include the design of distributed database communication middleware, the design and technical realization of message middleware and its application in ticketing system. This paper introduces the inference engine model of database communication system.
3) Socket, IPC, multi-process and multi-thread programming technology are adopted. This paper discusses the above technology in detail from both theory and application.
