Presentation Overview:

Objective - To develop and design a distributed airline reservation system.

C# (for GUI), .NET sockets (client), BSD sockets (server) with C programming, MYSQL database, UNIX environment.

System Functionality:

Login required for all. System Administrator:- Add airline database/representative Airline Representative:

- Add/Delete specific flights

- View its own flights

- List all customers for specific flight

- Update the airline information (email, airline name, password etc.) Customers:- Register as a new user

- Make/Cancel/View reservations

- Update personal information

Project Features: BSD sockets (server): – well integrated with OS. .NET sockets (client) I/O multiplexing “select ()” used:

- application needs data sharing.

- less switching time between process. “MySQL” database. Encryption using MD5 algorithm. Multi-user authentication: – Login required. Data passed in binary format

- less BW usage, fast transmission of signals.

Project implementation code:

GUI: Login Example (Form - new_user_form.cs)1 button_login_click() /* function called upon Click of login button*/

2 String username = textBox_login_username.Text.Trim().ToString(); /* read the username string from the textbox */

3 String password = textBox_login_password.Text.Trim().ToString();

/* read the password string from the textbox */

Project implementation code (contd):GUI: Login Example (contd)

4 if (flight_resv_client.attempt_login(username, password, user_info) == true)

{ /* user was authentication successfully */

}

/* Do not do anything, authentication failed */

5. attempt_login() /* form a message that will sent to the server */

6. msg.msg_id = HTON(MSG_ID_LOGIN_USER)

7. msg.username = username

8. msg.password = password

9. Steam s = tcp_client.GetStream(); /* get TCP client data stream */

10. s.write(msg, msg.Length); /* send the message to the server */

11. s.Flush(); /* flush the buffer now */

12. s.Read(user_info, sizeof(user_info)

if (user_info.success != 0 ) {

/* user was authenticated was successfully */ return (true);

} else { /* user was not authenticated */

MessageBox.Show(user_info.error); return (false);

}
