21Airliner 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.

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”

25We learnt! • 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 hierarchyMutex/Semaphore

• Learnt about the difference between different calls in IPV4 and IPV6IPV4 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
