Abstract Factory Pattern
The Abstract Factory Pattern is a creational design pattern that provides an interface for creating families of related or dependent objects without specifying their concrete classes. It allows a system to be independent of how its objects are created, composed, and represented, promoting consistency among products and enabling easy switching between different families of objects. This pattern is particularly useful in scenarios where a system needs to be configured with multiple families of objects that must work together.
Developers should learn and use the Abstract Factory Pattern when building systems that require multiple families of related objects, such as GUI toolkits with different themes (e.g., light vs. dark mode), cross-platform applications needing OS-specific components, or database abstraction layers supporting various vendors. It ensures that objects from the same family are compatible and simplifies adding new families without modifying existing client code, enhancing maintainability and scalability in complex applications.
