Development And Application Of Distributed Database Communication Middle-ware In Ticketing And Reservation System For Chinese Railways

《Ticketing and Reservation System for Chinese Railways》(calledTicketing-System for short as follows) is one of important programs in ninth-fiveyears projects, and was listed as most key scientific research items by NSRI(National Scientific Research Institute) in l999. The contents of this thesis is oneimportant part of Ticket-System, mainly about design of distributed databasecommunication middle-ware. message middle-ware. their technical realization andticketing application. The reasoning model of database communication system ispresented, making use of diversified programming technique such as SOCKET.IPC. multi-process. multi-threading, which are particularly discussed in theory andpractice.
