UML diagrams for the Train Reservation project. Following are the different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the Train Reservation System.
UML Diagram for Train 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 Train Reservation Project. We have also explained this project’s data flow diagram (DFD).
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 types of Train tickets. Admin is who will manage the overall application; whereas the user or users can buy Train Ticket.
Component diagram for Train Reservation Project
The component diagram below shows the structural relations between components in a Train Reservation system. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely Train, booking, user, and account.
It shows how the user component connects to the other components while using the system. Once the user logs in to the system, the user can select the desired Train and place a booking following the payment process. While placing the booking, the user’s account details get accessed and the booking is confirmed after completing the payment.
Activity diagram for Train 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 Trains and can update all Train detail. Admin can view booking history and detail. Admin can manage payment and transactions.
Online users can browse or search Trains, view trains, and book tickets for the same. Users can view booking history at any time. Users can make payments for the booking and view the payment history.
Sequence diagram for Train 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.
Users can search for specific trains or choose a train according to their requirements and book a ticket for the same. Upon ticket availability, the user can continue for payment and confirm the booking.
Use Case Diagram for Train 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 trains and destinations of trains into the system. Whereas, users can access the system for booking purposes. Admin can access the booking reports and view the train details. The book ticket report holds the information about all the bookings made which can be accessed by the admin. Users can view their train booking details after logging in to the system.
DFD Diagram for Train 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 trains, manage prices of tickets, view bookings, check the availability of the Train tickets, etc.
Users, on the other hand, can book tickets online. Users can search for a particular Train, select a Train, and book tickets for the same. Users can also view their bookings and payment confirmation on the system.
