What is a Hotel Reservation?

hotel reservation system is a piece of software that allows clients to book directly with the hotel online, bypassing the need for middlemen. It enables guests to design their vacation at their leisure.

It’s a software application that shows your live pricing and inventory across all of your channels in real-time, allowing guests to choose their travel dates and complete their reservations.

What is a Component Diagram in UML?

A component diagram in the (UML) Unified Modeling Language shows how parts are wired together to explain the parts of the hotel reservation system. They are used to show the structure of any kind of system.

The UML component diagram shows how the hotel reservation 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.

The Component Diagram for Hotel Reservation System

This component diagram of hotel reservation system is the illustration of the components of every hardware and software node. The component diagram below is a detailed illustration of hotel reservation system using the UML diagrams model.

This component diagram shows the structure of the hotel reservation, which consists of the software components and their interfaces, user device, and the database. Their dependencies explain how they work together. You can use a component diagram 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.

Hotel Reservation System Component Diagram (Explanation)

The Hotel Reservation 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 reservation system operation.

The system’s component diagram has 8 components. Each of these components has its part in the hotel reservation system. The system’s components were the customer, admin, system database, inquiries interface, reservation module, status and payment, check reservation details, and update transaction details.

This diagram shows several interfaces that are provided and required. The dependencies on each component are explained through the lines and arrows drawn in the diagram. The required and provided interfaces were declared by the line that has a circle with a semi-circle head.

Characteristics of Component Diagram:

  • In component-based development, they describe systems that have a service-oriented architecture.
  • It shows how the code itself looks.
  • It can be used to focus on the relationship between the parts while hiding the specifics.
  • Help stakeholders understand how the system being built works and how it will be used.

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 hotel 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 component diagram for hotel reservation system.

  • 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 hotel reservation system. 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.

    A component list contains the set of interfaces that a component can use or realize. Components also need interfaces to do their job. It is part of a system that protects the things inside. They are the parts of a system that make sense and play a big part in how a system works.


You need to know the diagrams used to design and develop the Hotel 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.

The component diagram shows how a system is put together. During the design phase, software artifacts (classes, interfaces, etc.) of a system are put together into different groups based on how they work together. Now, these groups of things are called parts. Check out our Related and Recommended Articles for more Learning and Information.
