The document outlines three lab exercises focused on creating state transition diagrams for different systems: an Airline Reservation System, a University Course Registration System, and an Online Shopping System. Each exercise includes specific assumptions about user interactions and system requirements, such as payment verification for reservations and a minimum number of students for course initiation. The diagrams illustrate the flow of activities and transitions necessary to complete each process successfully.

activities involved for making Reservation, Changing Reservation and
Passenger Checking in for flight. ,Also clearly write down your
assumptions.

Assumptions:

of the previous process which imitates normal flight reservation
systems.
● The flight is booked if and only if the payment is verified. If it is not
verified it asks to enter correct details.
● The user is required to enter his ticket details to modify the current
reservation.

their point of view.
● This diagram only allows access to students logged in through cloud id’s
● The registrations are automatically closed as soon as the number of students reach 10.

Q3) Draw State Diagram of online shopping system. Consider any website and define
states and their transition to successfully place order, also define appropriate start and
exit states. Also clearly write down your assumptions
Q3 )Draw State Diagram of online shopping system. Consider any website and define states and
their transition to successfully place order, also define appropriate start and exit states. Also
