Component Diagram for Online Food Diagram System

The component diagram for online food ordering system in UML is used to show how the components of the food ordering system coordinate and cooperates to function properly. A component diagram shows how the software’s parts are organized and how they depend on each other. This diagram gives a high-level look at the parts of an online food ordering system.

Components of an online food ordering system component diagram can be software or hardware. They could be a database, a user interface, or something else that helps the food ordering system work.

Component Diagram of Online Food Ordering System Description

An online food ordering system is a piece of software that allows restaurants, coffee shops, and bars to take orders over the internet. In most cases, customers can choose and pay for food before the kitchen is told that an order has been made.

The system includes a website or app that allows customers to look at the menu and order food, as well as an admin interface that lets restaurants get and send orders to customers, so they can get and send them food.

In an online food ordering system, a consumer searches for a favorite restaurant, which is usually categorized by cuisine, and then selects from available items, as well as delivery or pick-up options. Payment can be made in a variety of ways, including credit card or cash, with the restaurant remitting a portion of the proceeds to the online food delivery service.

What is Online Food Ordering System Component Diagram in UML?

A component diagram in the (UML) Unified Modeling Language shows how parts are wired together to create bigger parts of the food ordering system. They are used to show the structure of the food ordering system.

The UML component diagram shows how a software system will be made up of 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 of Online Food Ordering System

This component diagram of online food ordering system is the illustration of the components of every hardware and software node. The component diagram below is a detailed illustration of the deployment diagram for online food ordering.

This component diagram shows the structure of the online food ordering system, which consists of the software components and their interfaces, and 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.

Online Food Ordering System Component Diagram (Explanation)

The Online Food Ordering 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 food ordering operation.

The component diagram of food ordering system has 7 components which are food database, transaction database, menu list, place order, payment, delivery, and the user. The components inside the package are the required interfaces that are dependent on the provided food database component and vice versa for the transaction database. The included components were just based on the main function of the system.

The dependencies on each component are explained through the lines and arrows drawn in the diagram. This design can be modified or can be innovated to achieve the required functions of the food ordering system.

Characteristics of Component Diagram:

  • In component-based development, they are used to describe systems that have a service-oriented architecture.
  • 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 food ordering 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 for Food Ordering System

Time needed: 10 minutes.

Here are the steps in developing the food ordering 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 food ordering 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 the form of 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 Food Ordering 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.

Component diagrams show 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.
