Abstract Factory Model V

Definition: Provides an interface that creates a series of related or interdependent objects without specifying their specific classes. (There are constraints between the created objects)

The essence of Abstract factory model: The realization of selecting product clusters

Advantages: Separation of interfaces and product families makes it easy to switch product clusters

Cons: Not easy to expand new products, easy to create class hierarchy complex

Factory method patterns are generally used in a single product that is not associated with a product, whereas abstract method patterns are generally used when there is a link between products.
