This presentation summarizes a distributed airline reservation system created by a group of students. The system allows customers to make, cancel, and view flight reservations, and allows airline representatives and administrators to manage flights and user accounts. Key aspects include a MySQL database to store user and flight data, .NET sockets for the client interface, BSD sockets for the server, and C# code to build the graphical user interface. The presentation demonstrates screenshots and discusses challenges in integrating the different programming languages and databases.

3. 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.

4. 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

7. 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.

8. 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 */

9. 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);
}
