Basically a class diagram is a type of diagram in programming. It is object-oriented which is used to represent the structure and relationships between classes in a system.
This diagram shows the classes in the system along with their attributes and methods. This model represents relationships between classes such as inheritance and associations. Class Diagrams are different from ERDs. See how Entity-Relationship Diagrams and UML Class diagrams differ

Class Diagram Function
The role of class diagrams really helps programmers and development teams in many ways. The process of designing, understanding and developing systems can be done more easily and efficiently.
Mistakes made during work will also be minimized. That way the quality of the system can be developed better.
Programmers are better able to produce the best applications and systems in a more structured manner through the application of class diagrams.
Examples and Functions of Class Diagrams are as follows
The main function of class diagrams is to reduce programmer performance in creating systems.
Examples of using class diagrams are in building library applications.
In this class diagram, there are several classes. For example, the Book class, Member class, Loan class, and Library class.
Each class has its own attributes and methods.
Class Book, for example, has attributes such as title, author, and publisher, as well as borrow and return methods.
This diagram also shows the relationships between classes.
In the example class diagram in a library application, the Member class has an association with the Loan class. This code indicates that a member can borrow a book from the library.
Class Loan also has an association with class Book. This means that it shows a loan related to a book.
The diagram also shows inheritance between classes.
In the library application example, the Book class can be inherited by the FictionBook class or the NonFictionBook class. They have specific attributes and methods for each type of book.
In essence, class diagrams are a very important tool in developing object-oriented applications.
He also helps with the system documentation process. So new developers can easily understand the future flow of the system.
