Dependency
Dependency represents a relationship where one class (client) depends on another class (supplier) for its functionality. If the supplier class changes, the client class may need to be modified. For example, a “Person” class may depend on a “Car” class to drive, but the person can exist without the car.
These relationships help in modeling the interactions and dependencies among objects in a system, facilitating a better understanding of the system’s structure and behavior in OOAD.
What are the Relationships among Objects in OOAD?
In Object-Oriented Analysis and Design (OOAD), the relationship among objects is fundamental to modeling the behavior and structure of a system, and Object diagrams are used to depict instances of classes and their relationships at a specific point in time. There are several types of relationships among objects:
