Class Diagram Assignment

UML Class diagram provides a conceptual model

of the system in terms of entities and their

relationships. It is used for requirement capture;

end-user interaction and detailed class diagrams

can be used for developers. Consider that you are

asked to model Airport Management System. The

airport is a complex system in which thousands of

domestic and international flights function every

day and it needs proper planning and execution to

make it a management system. In this

assignment, you will need to draw a class

diagram (via Draw.io website) containing the

following classes with their attributes and

methods as below:

Classes:

AirportManagement - This class

contains the overall details of the

airport.

TicketCounter - It allows the

passengers to buy the ticket and do pay

for a ticket.

Flight - This contains all the flight

details in an Airport.

Employees - Employees can be two

types - Airport and Airplane Employee.

This class is the parent class of two

subclasses - Airport Employee and

Airplane Employee

AirportEmployees - This class is the

child class of Employees. It describes

the employees working in the airport. It

contains their designation and

departments like customs, ticket, food,

etc.

AirplaneEmployees

- This class is the

child class of Employee and contains

the designation like Air Hostess, Pilot,

etc. It indicates the employees working

inside airplanes.

Runway - This contains the runway

details and it also tells whether the

particular runway is occupied by any

flights.

Passengers - This class contains the

passenger details.

NoticeBoard - This class contains the

current flights and the flights which are

yet to arrive and depart on a particular

day.

Luggage - This class holds the details

of luggage for a particular passenger

Attributes:

AirportManagement-AirportName,

CityName, Area

TicketCounter-Ticketld.

PassengerId, Source, Destination, Price,

Flightld.

Flight - Flightld, FlightName,

Capacity, StartingTime, ReachingTime,

Source, Destination, Price

Employees - Employeeld,

EmployeeName, EmployeeSalary

AirportEmployees-Designation,

Department

Airplane Employees-Designation

Runway- RunwayNumber,

FlightName, OccupiedStatus

NoticeBoard - Flightld, FlightName,

ArrivalTime, Departure Time, Source

Destination

Luggage - Luggageld, Passengerld,

Flightld, NoOfLuggages

Methods:

AirportManagement:

open -This indicates

whether the airport is

functioning or not and

helps us to start and stop

the airport functioning.

TicketCounter:

TicketDetailsO

- This

method displays the

details of our ticket and

the flights available

along with their prices.

BookTicket0 - This

method is to book the

ticket

Flight:

FlightDetailsO

This

method is to display all

details of the flight along

with the number of

tickets booked for each

flight.

Employees :

EmployeeDetailsO

This method is used to

display the details of the

employee along with

their designation.

Runway:

Runway Details- This

method gives the

runway length, flights

that have reserved the

runway, and the flight

which is currently on

that runway.

isOccupied0 - It says

whether the runway IS

occupied or not.

Passengers :

PassengerDetails

This method displays the

entire details of the

passengers in the airport.

Checkin- This

method is to check in to

the flight.

NoticeBoard:

Details - This method

displays the details of all

the flights which are in

the airport and also

displays the timings and

details of the flights

which have departed

already and which are

going to arrive soon.

FlightStatus-

This

method displays the

status of a particular

flight and also says if the

flight is delved or departing soon and also

the number of

passengers.

Luggage:

LuggageDetails-

This

method displays the

details of all the luggage

associated with a

particular passenger.

LuggageStatus - This

method is used to

indicate the status of the

luggage and says

whether it is checked

and shipped.

There is an association relationship

exists

between

passengers and employees because

passengers need employees and employees serve

passengers, but they both exist in their own space.

Also, there are

some classes that follow

aggregation like Flight and Passengers, Flight

and Notice board and Flight and Runway.

Other classes like Passengers, Notice board, and

runway are related to flight in some way but they

can also exist without a flight and one flight can

be replaced by another flight. Here passengers

and luggage follow a composition relationship

because luggage cannot even exist without its

owner (passengers)
