Plane ticket system design requirements: login system interface, account number, password; Establish flight information function; Check the air ticket information from Zhengzhou to a terminal; Air ticket purchase function; Add the function of ticket purchaser information; Display ticket purchaser information function; Cancellation of air tickets;
