  1. Familiarize Class Diagram Components

    Class Name: The name of the class appears in the upper portion.
    Class Attributes: The class’s attributes are found in the middle portion.
    Class operations: are included in the bottom part (methods).
    Class Connections: Depending on the access modifier, each class has a different level of access (visibility).
    The following are the access levels and the symbols that correlate to them:
    Public (+)
    Private (-)

    Derived (/)
    Protected (#)

    Static (underlined)
    Package (~)

  2. Determine the targeted users

    After getting used to the symbol, you’ll need to decide who you want to use it. Besides, your project will be used by the people you want to use it.

  3. Analyze the activities included

    When making a class diagram, it is very important to analyze. It will help you figure out how the diagram works and keep you from making mistakes you don’t want to.

  4. Plot the Class Diagram

    To plot the class diagram you will need the class name, its attributes, methods, and their access (visibility). You will base the diagram on the evaluated information to have the exact Class Diagram.

Example of Simple Class Diagram for Online Shopping with Explanation

The Simple Class Diagram for the Online Shopping System is given, along with an explanation of what it means. In addition, this Class Diagram tells you everything you need to know about the class’s methods and properties. It also shows how the system’s classes are related to each other. Also, here, I’ll show you an example of how to build a class diagram and match its attributes and methods. This made with a simple idea that comes from the common task of shopping online.



You need to know how the Online Shopping System was designed and built using diagrams. That’s because you can’t make a system that works perfectly without it. But if you make this class diagram, you’ll know what classes and situations the system should be able to handle. You will also find the necessary processes and link them to the other UML Diagrams.
