UML diagrams for the Airline Reservation project. Following are the different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the Airline Reservation System.
UML Diagram for Airline Reservation System
We’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the Airline Reservation Project. We have also explained the data flow diagram (DFD) for this project.
The airline reservations system is a web application that builds to automate the ticket booking system of airlines. An online platform for the customer to check the flight details and book the ticket as well.
Component diagram for Airline Reservation Project
Component diagrams are used to visualize the organization and relationships among components in a system. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely flight, booking, user, and account.
It shows how the user component connects to the other components while using the system. Everything from the account details to flight booking to payment flow can be seen in the component diagram.
The user can select the desired flight and book a ticket following the payment process. While booking, the user’s account details get accessed and the booking is confirmed after completing the payment.
Activity diagram for Airline Reservation Project
Activity diagrams in UML display the functionalities of various activities and flow in management processes and software systems. The flow in the activity diagram can be sequential, branched, or concurrent.
Admin can view the list of users. Admin can manage the category of flights and can update all flight detail. Admin can view booking history and detail. Admin can manage payment and transactions.
The user can browse or search flights, view specific flights, book them, view, add to cart, and checkout. Users can view booking history at any time. Users can make payments for the booking and view the payment history.
Once the user login to the system, the flight list can be selected to see the flights available for specific destinations. Users can also search flights accordingly. As soon as the user clicks on the book ticket, ticket availability message will be displayed incase the ticket for a particular flight is not available. If the ticket is available, the user can go on and make payments for the same.
Sequence diagram for Airline Reservation Project
Sequence diagrams in UML are used to illustrate the sequence of messages between objects in an interaction. A sequence diagram consists of a group of objects that are represented by lifelines and the messages that they exchange over time during the interaction.
Online users can search for flights, view the price of a selected flight, add the flight to the booking cart, and make payments for the booking.
Here, Users can search for specific flights or choose a flight according to their requirements and book the ticket for the same. Upon ticket availability, the user can continue for payment and confirm the booking.
Use Case Diagram for Airline Reservation Project
A UML use case diagram can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed.
As you can see from the examples below, use cases are represented by oval shapes, and the lines then show at which point an actor/user participates and interacts with their corresponding use case. You can see where each actor is involved within the entire process (and where they’re excluded).
For example, Admin will be able to add multiple flights and destinations of flights into the system. Whereas, users can access the system for booking purposes. Admin can access the flight reports and view the flight details. The book ticket report holds the information about all the bookings made which can be accessed by the admin. Users can view their flight booking details after logging in to the system.
DFD Diagram for Airline Reservation Project
A data flow diagram represents the flow of information for any process or system. It shows the system with its relationship to external entities. Here, we can see how the users and the process flow work in a system.
After logging in, Admin and User will land on the home page where they can manage their profiles. Admin can add, view flights, manage prices of tickets, view bookings, check the availability of the flight tickets, etc.
Users, on the other hand, can book the tickets online. Users can search for a particular flight, select a flight, and book tickets for the same. Users can also view their bookings and payment confirmation on the system.
