Component Diagram for Online Shopping Cart | UML

The UML component diagram for online shopping cart is used to show how the parts of the online shopping work together to make the system operate correctly. This diagram visualizes the software’s parts, how are they organized, and how they depend on each other. This gives a high-level look at the parts of a system.

The components of online shopping cart component diagram could be a part of software or hardware. They could be a database, a user interface, or something else that helps the hotel reservation system work.

What is an Online Shopping Cart?

Shopping cart software is part or equal to an e-commerce software that runs on a web server and allows visitors to an Internet site to choose things for purchase. Customers who shop online can create a wish list of products to buy using the software. Its goal is to aid online merchants with big client records by providing at least a simplified self-service option.

The entire purchasing process is automated with a shopping cart system. This statement explains that there is less work for online sellers and a simple transaction for online customers using a shopping cart. Sellers can save time, and money, and keep the customers happy by delegating the task to the shopping cart.

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 online shopping cart. 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 Online Shopping Cart

This component diagram of online shopping cart is the illustration of the components of every hardware and software node. The component diagram below is a detailed illustration of online shopping cart using UML diagrams model.

This component diagram shows the structure of the shopping cart, 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.

Online Shopping Cart Component Diagram (Explanation)

The Online Shopping Cart 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 hotel reservation system operation.

The system’s component diagram has 8 components. Each of these components has its part in the online shopping cart. The system’s components were the sellers and/or admin’s device, shopper’s device, user login interface, product database, carts database, sales database, orders database and transaction database.

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 online shopping cart 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 online shopping cart.

  • 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 online shopping 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.

    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.

Conclusion

You need to know the diagrams used to design and develop the Online Shopping Cart. 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.
