Component Diagram for Railway Reservation System | UML

The Component Diagram for Railway Reservation System is a diagram used to show how the parts of the railway reservation system work together to make the system run efficiently.

In addition, this diagram visualizes the component in a system on how they organized, and how they depend on each other. This gives a high-level look at the parts of a system.

What is the Purpose of the Railway Reservation System?

The railway reservation system enables passengers to inquire about available tickets according to their location and destination, avail of ticket bookings and cancel tickets when needed, and see the status of their booked tickets, and other transactions.

The Component Diagram for Railway Reservation System

This component diagram of railway reservation system is the illustration of the components of every hardware and software node in a page layout. The component diagram below is a detailed illustration of other diagrams for the System.

This component diagram shows the structure of the railway reservation system, which consists of the software components and their interfaces, user information, and the database. Their dependencies explain how they work together. You can use component diagrams to show how software systems work at a high level, or you can use them to show how each component works at a lower level, like in a package.

Benefits of using Component Diagram

As complicated as it looks, the component diagram is very important when you’re building your system because it shows how everything works together. Here are the benefits of designing the railway reservation system component diagram:

  • Imagine how the system looks in real life.
  • Pay attention to the system’s parts and how they work together.
  • Pay attention to how the service behaves when it comes to the interface.

Steps in Developing Component Diagram

Time needed: 10 minutes

Here are the steps in developing the railway reservation system component diagram.

  • Finalize the Function and Processes of the Software

    The first step in developing the component diagram is finalizing the processes and functions of the software. This activity will help programmers analyze what are the things needed to complete the railway reservation process. Then the finalized processes or functions will be the base concept in designing the system’s component diagram.

  • Put the Components included

    A component is a piece of the system that makes sense in terms of logic. It’s a little more abstract than classes. There are tabs or the word “Component” written on top of the name of the component to help you tell it apart from a class.

    The component symbol is used for a person or thing that needs to do a stereotype function. It gives and takes behavior through interfaces, as well as through other parts. Components can be grouped into a node or another component and can be only one component.

  • Add the Dependencies (Ports and interfaces)

    A dependency is a relationship in which one component needs the information and services of another component, but not always the other way around. To show that one component is relying on another, you should make a connection.

    The component’s port is a feature that indicates where the component and its environment meet. In this picture, ports are shown in small squares on the sides of classifiers. It is created when one thing is needed for another thing to work. There is an “include” statement in the makefile for the component that is dependent on the other component.

    Interfaces show how components are wired together and how they work together. When a component needs a certain interface, the assembly connector lets you connect it to another component that already has that interface. It looks like a semi-circle and a line.


In conclusion, you need to know the diagrams used to design and develop the Railway Reservation System. This method is to perfectly create a fully-functional system without unwanted errors and avoid mistakes in development.

A component diagram will help you know the components of software and hardware that the project should possess. Not only that, you will find out the needed consideration for the software to work perfectly.
