UML diagrams for the Online Bus Ticket Booking project. Following are the different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the Online Bus Ticket Booking System.
The Online Bus Ticket Booking system is built to support all the functionality related to the process of booking, buses, tracking, and managing. We will be understanding the functionality through UML diagrams in this article.
UML Diagram for Online Bus Ticket Booking System
In this article, several structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the Online Bus Ticket Booking Project are compiled together. We have also explained the data flow diagram (DFD) for this project.
With the help of these diagrams, one can get a better understanding of the project. This web application is developed to provide users with an online medium where they can book different Bus tickets. Admin is who will manage the overall application; whereas the user or customers can book Bus Ticket.
Component diagram for Online Bus Ticket Booking Project
The component diagram below shows the structural relations between components in an Online Bus Ticket Booking system. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely Bus, booking, customer, and account.
It shows how the user component connects to the other components while using the system. Everything from the account details to Bus booking to payment flow can be seen in the component diagram.
Users can register themselves and then check seat availability, book tickets, and make payments online, While placing the booking, the users’ account details get accessed and the booking is confirmed after completing the payment.
Activity diagram for Online Bus Ticket Booking 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 who is the main user in this application has the responsibility of adding buses, seat availability, bus fare, source, destination, etc.
Online customers can browse or search items, view specific bus details, book them, view, add, and checkout. Users can view booking history at any time. Customers can make payments for the booking and view the payment history.
Sequence diagram for Online Bus Ticket Booking Project
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. Sequence diagrams in UML are used to illustrate the sequence of messages between objects in an interaction.
A user can register first using their name, contact number, and address and also can manage their profile. The user can log in to the system using their names & contact number. Users can search for buses and view if tickets are available for the same. Users can view/track their booked tickets, payment status, history, etc.
Use Case Diagram for Online Bus Ticket Booking 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. We can see where each actor is involved in the entire process and which use case each actor can access.
From the below example, we can see that Admin will be able to add buses, view bus reports, and different buses and destinations of the bus into the system. Whereas, users can only view the bus list and access the system for ticket booking purposes.
DFD Diagram for Online Bus Ticket Booking 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 buses, manage prices of tickets, view bookings, check the availability of the bus tickets, etc.
Users, on the other hand, can book the tickets online. Users can search for a particular bus, select a bus, and book tickets for the same. Users can also view their bookings and payment confirmation on the system.
