UML diagrams can be used as a way to visualize a project before it takes place or as documentation for a project afterward. But the overall goal of UML diagrams is to allow teams to visualize how a project is or will be working, and they can be used in any field, not just software engineering.

How do you identify classes in class diagram?

Here are the steps you need to follow to create a class diagram.

  1. Step 1: Identify the class names. The first step is to identify the primary objects of the system.
  2. Step 2: Distinguish relationships. Next step is to determine how each of the classes or objects are related to one another.
  3. Step 3: Create the Structure.
