Classification of design patterns and KISS principle

Classification based on creation/structure/behavior.

Creational Patterns provide us a way to decouple the client from the objects that it needs to instantiate.

• Singleton
• Factory
• Abstract factory
• Prototype
• Builder

Structural patterns help us to compose classes or objects into larger structures

• Composite
• Decorator
• Facade
• Proxy
• Adapter
• Bridge
• Flyweight

Behavioral Patterns dictates how classes and objects interact with each other and distribute the responsibilities

• Template Method
• Strategy
• Observer
• Command
• Iterator
• Chain of responsibility
• Visitor, Mediator and Interpretor
• State

Secondary classification based on classes and objects.

Class patterns describe how relationships between classes is defined via inheritance and these relationships are established at compile time

• Template Method
• Factory Method
• Adapter
• Interpretor

Object patterns describe relationships between objects via composition and these relationships are created at runtime which is more dynamic and flexible

• Singleton
• Abstract Factory
• Composite
• Decorator
• Command
• Observer
• Strategy
• … all others go here

It doesnt matter how any patterns we know, always make sure to keep the code simple. KISS PRINCIPLE keep it simple stupid principle
