Answer All the Questions & Draw UML diagrams for the given Application-Scenarios

A. Consider the following Scenario for Online-Reservation system for Railway-Company :

Railway Reservation System is a system used for booking tickets over internet.

Any Customer Can book tickets for different trains. Customer can book a ticket

only if the tickets are available. Customer searches for the availability of tickets

then if the tickets are available he books the tickets by initially filling details in a

form. Tickets can be booked in two ways by i-ticket or by e-ticket booking.

In case of i-ticket booking, customer can book the tickets online and the tickets are

couriered to Particular customer at their address. But in case of e-ticket booking

and cancelling tickets are booked and cancelled online sitting at the home and

customer himself has to take print of the ticket but in both the cases amount for

tickets are deducted from customers account.

For cancellation of ticket, the customer has to go at the reservation office then fill a

cancellation form and ask the clerk to cancel the ticket then the refund is

transferred to customer account. After booking the ticket, the customer has to

checkout by paying fare amount to clerk.

1) Draw a use-case diagram for describing the functional requirements of the above system.

2) Draw Class-diagram show the Class attributes, operations, Generalization, Association, Multiplicity and Object Diagram

3) Draw Object Diagram for the above Scenario.

B. For the given below Elevator System Scenario draw the following UML diagrams:

4) Collaboration diagram including constraint tools

5) Activity diagram including Vertical swimlane, fork, join, merge,decision tools

A product is to be installed to control elevators in a building with m floors. The problem concerns the logic required to move elevators between floors according to the following constraints:

Each elevator has a set of m buttons, one for each floor. These illuminate when pressed and cause the elevator to visit the corresponding floor. The illumination is canceled when the elevator visits the corresponding floor.

Each floor, except the first floor and top floor has two buttons, one to request and up-elevator and one to request a down-elevator. These buttons illuminate when pressed. The illumination is canceled when an elevator visits the floor and then moves in the desired direction.

When an elevator has no requests, it remains at its current floor with its doors closed.

The basic course of Action for elevator scenario:

Passenger presses floor button (that is the button on the wall).

Elevator system detects floor button pressed.

Elevator moves to the floor.

Elevator doors open.

Passenger gets in and presses elevator button (that is the button in the cabin panel).

Elevator doors close.

Elevator moves to required floor.

Elevator doors open.

Passenger gets out.

Elevator doors close.
