Hello, Itsourcecoders.

Today, I will be showing you different examples of UML component diagrams.

This will help you create your own if you’re having a hard time.

So, without further ado, let’s get started!

Component Diagram

A Component Diagram is a diagram used to show how the parts of a system work together to make the system run efficiently.

This diagram visualizes the components in a system, how they are organized, and how they depend on each other.

This provides a high-level look at the parts of a system.

Apart from that, it illustrates the components of every hardware and software node in a page layout.

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.

List of UML Component Diagram Examples in Different System Projects

Here is the list of UML Component Diagram Examples in Different System Projects, which you may use as your basis.

Maybe the system you will be creating is here.

1. Component Diagram for Airline Reservation System

The Airline Reservation System is a project management software which used not only to make flight reservations but also to assist with many airline management activities and to meet the needs of consumers from the initial booking through the flight processing.

This component diagram shows the structure of the airline system, which consists of the software components and their interfaces, accounts database, transaction information, and financial information.

However, the image above is not complete and there are no dependencies that explain how they work together.

2. Component Diagram for Railway Reservation 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.

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.

However, the image above is not complete and there are no dependencies that explain how they work together.

3. Component Diagram for Hospital Management System

A Component Diagram is a (UML) Unified Modeling Language shows how parts are wired together to clarify the parts of the software and hardware in the system.

They are used to show the structure of the hospital management system.

However, the image above is not complete and there are no dependencies that explain how they work together.

4. Component Diagram for Hotel Reservation System

The hotel reservation system UML component diagram is used in object-oriented programming to group classes together based on their common purpose.

This way, the developer and others can see how a project is progressing at a high level.

However, the image above is not complete and there are no dependencies that explain how they work together.

5. Component Diagram for Login System

The Login System UML component diagram explains the sketch of the required software and hardware components and the dependencies between them.

These components are labeled to clarify their part in the system’s operation.

They were represented by symbols that explain their function and role in the overall processing system operation

However, the image above is not complete and there are no dependencies that explain how they work together.

6. Component Diagram for Point of Sale System

A component diagram in the (UML) Unified Modeling Language shows how parts are wired together to explain the parts of the point of sale system.

They are used to show the structure of any kind of system.

The UML component diagram shows how a POS system comprises a set of deployable components, such as dynamic-link library (DLL) files, executable files, or web services.

Using well-defined interfaces, these parts communicate with each other and keep their internal details hidden from each other and the outside world.

However, the image above is not complete and there are no dependencies that explain how they work together.

7. Component Diagram for Attendance Management System

The system’s component diagram has 7components. Each of these components has its part in the attendance management system.

The system’s components were the system access, student database, attendance database, absent records, present records, teacher’s device, and the student.

The image above is not complete and there are no dependencies that explain how they work together.

8. Component Diagram for Restaurant Management System

The component diagram of the restaurant management system has 7 components which are the system database, online ordering, food details, delivery options, contact information, payment options, system access, and payment account.

This diagram shows several interfaces that are provided and required.

The required interfaces (components) were on the semi-circle side symbol of the dependency and the provided were on the full-circle side.

The image above is not complete and there are no dependencies that explain how they work together.

Maybe the Component Diagram for your system has already been created here.

Conclusion

So, we’re finally done discussing the UML Component Diagram Examples.

With this knowledge, you will be able to create your own component diagram based on your system.
