Introduction to Class Diagrams
Class diagrams represent the static structure of a system, showing classes, attributes, operations, and relationships.
Class Diagram Notation
Key elements include classes, attributes, operations, associations, and multiplicity. Symbols like rectangles and lines denote these elements.
Understanding Classes
A class is represented by a rectangle divided into sections for the class name, attributes, and operations.
Relationships in Class Diagrams
Classes are connected by associations, aggregations, compositions, and inheritance, represented by different lines and arrows.
