The Flow Chart
 Client is constantly
reading the command
line and writing it to the
server
 Server will process the
information depending

Customer Database
 Customer information
 Add new Customer
 Update customer information

Customer Database (Demo) 12

The System Admin
 The sysadmin handles both the flights and the airliner data to meet
efficient services
 Adding, removing, or updating flights/airliner
 adding, deleting and backup the database.

The Commercial Airliner
 Acts as a flight customer service agents.
 Notifies System admin if there are any changes in Flight details.
 Has the authority to add flights, Update, delete and display flight details.
 Provides information about Seat availability, Baggage information and on-
board facilities.

Airliner implementation:
 Database handling is done using SQLite 3.
 Database includes Itinerary comprising the flight number, Seat availability,
Travel class, Baggage info, and on-board facilities.
 Provides the database to sysadmin and notifies if there is any update in
flight details.

Airliner Demo 22

Hurdles:
 Figuring out the “n" terminated string, had to be read correctly.
 “The While problem”
 Moving on from File based implementation: “The Database”
 “Backward Traversing”
 Databases + BSD socket program : “The Merge”
 “Bringing it all together”
23

Enhancements planned:
 IPV6
 Encryption
 Winsock
 State information

We learnt! 25
• Learnt programming using BSD sockets.BSD Sockets
• Concept of threading.
• Memory and resources sharing.
Multithreading
• Communication between them.
• Design and implementation.Client-Server
• Implementing a client-server at an enterprise level, takes a lot of planning and design, this project gave us an
overview as to how a client server model can be implemented at an enterprise level.Implementation
• Learnt about the behaviour of the model at different hierarchy
Mutex/Semaphore
• Learnt about the difference between different calls in IPV4 and IPV6
IPV4 vs IPV6
• Got to learn about creating and passing queries to the database using SQL.
Database
• The most important task of all is to work as a team effectively, we managed to emerge as a better team.Team Work

Thank You! 26
