title: Bus ticketing reservation systems
body: <p>I am planning to make an online bus ticket reservation systems . In this, the ticket agent as well as the online user can book the tickets available . But I am stuck while I am building my flow chart . Buses with same numbers can go to and fro journey,ie a bus with number AS 1234 can go to X and Y in both direction  . So how I will be able to search the bus from X and Y only,because that bus will be entered for both direction in database . Thanks</p>
