What does a class diagram show between classes?

Classes in a class diagram correspond with classes in the source code. The diagram shows the names and attributes of the classes, connections between the classes, and sometimes also the methods of the classes. Next we will get familiar with creating and reading class diagrams using UML.

When do you need to draw a class diagram?

Why are class diagrams important in Object Oriented Analysis?

Object-oriented methodologies work to discover classes, attributes, methods, and relationships between classes. Because programming occurs at the class level, defining classes is one of the most important object-oriented analysis tasks. Class diagrams show the static features of the system and do not represent any particular processing.
