Class Diagrams

Class diagrams are a fundamental tool in object-oriented modeling, used to represent the structure of a system by showing the system's classes, their attributes, methods, and the relationships among objects.

Class diagrams in Modeldraw allow you to:

• Visualize the static structure of your system

• Model relationships between different classes

• Define attributes and methods for each class

• Represent inheritance, associations, and dependencies
