You are tasked with designing a system where the creation of product objects needs to be handled differently based on the context or type of product requested, without exposing the instantiation logic to the client. The system should also support the creation of families of related products. Which combination of creational patterns would best address these requirements?

Study Notes
- Design Patterns are solutions to common problems in software design
- They are customizable blueprints
- They solve recurring design problems in code
Design Pattern Elements
- Pattern Name
- Problem
- Solution
- Consequences
Categories of Design Patterns
- Creational: Focuses on object creation mechanisms.
- Structural: Focuses on assembling objects and classes into larger structures.
- Behavioral: Focuses on assigning responsibilities between objects.
Creational Patterns
- Singleton
- Factory Method
- Prototype
- Abstract Factory
- Builder
Singleton Design Pattern Structure
- This ensures a class only has one instance, and provides a global point of access to it.
Factory Method Design Pattern Structure
- This provides an interface for creating objects in a superclass, and allows subclasses to alter the type of objects that will be created.
Prototype Design Pattern Structure
- This involves creating new objects by copying an existing object, known as the prototype
Abstract Factory Design Pattern Structure
- This offers an interface for creating families of related or dependent objects without specifying their concrete classes.
Builder Design Pattern Structure
- This separates the construction of a complex object from its representation, allowing the same construction process to create different representations.
Structural Patterns
- Adapter
- Bridge
- Composite
- Decorator
- Facade
- Flyweight
- Proxy
Adapter Design Pattern Structure
- This converts the interface of a class into another interface clients expect
- Adapter lets classes work together that could not otherwise because of incompatible interfaces
Bridge Design Pattern Structure
- This decouples an abstraction from its implementation so that the two can vary independently
Composite Design Pattern Structure
- This composes objects into tree structures to represent part-whole hierarchies
- Composite lets clients treat individual objects and compositions of objects uniformly
Decorator Design Pattern Structure
- This attaches additional responsibilities to an object dynamically
- Decorators provide a flexible alternative to subclassing for extending functionality
Facade Design Pattern Structure
- This provides a unified interface to a set of interfaces in a subsystem
- Facade defines a higher-level interface that makes the subsystem easier to use
Flyweight Design Pattern Structure
- This uses sharing to support large numbers of fine-grained objects efficiently
Proxy Design Pattern Structure
- This provides a surrogate or placeholder for another object to control access to it
Behavioral Patterns
- Iterator
- Observer
- Strategy
Iterator Design Pattern Structure
- This provides a way to access the elements of an aggregate object sequentially without exposing its underlying representation
Observer Design Pattern Structure
- This defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically
Strategy Design Pattern Structure
- This defines a family of algorithms, encapsulates each one, and makes them interchangeable
- Strategy lets the algorithm vary independently from clients that use it
