Factory = รูปแบบการสร้าง objects โดยไม่ hardcode class

Why use Factory:
   - Decouple object creation from usage
   - Create objects based on runtime conditions
   - Hide complex creation logic
   - Easy to extend with new types

Types:
   1. Simple Factory - function or class that creates objects
   2. Factory Method - subclass decides which class to create
   3. Abstract Factory - create families of related objects

When to use:
   - Object type determined at runtime
   - Complex object creation
   - Need to add new types easily
   - Creating objects from configuration
