Class Relationships

The following relationship types are used in the UML diagrams throughout this repository:

Aggregation - Describes a "whole-part" relationship where the "part" can exist independently of the "whole". The diamond is placed on the "whole" side.

Composition - A subtype of aggregation in which the "parts" cannot exist separately from the "whole".

Dependency - A dashed arrowhead line indicates a class that instantiates objects of another class. The arrow points to the class of the instantiated objects.

Generalization - Represents inheritance or interface implementation relationships. The arrow points to the superclass or interface.
