Scheme

Single Responsibility	Interface Segregation
🔸 Only one reason to change 🔸 Only one responsibility	🔸 Client should not be forced to implement methods it does not use 🔸 Fat Interfaces should be decoupled by its responsibilities
Open Close	Liskov’s Substitution
🔸 Close for modification 🔸 Open for extension	🔸 Extended class should be substitutional with its Base class 🔸 Modification should not affect Base behavier
Dependency Inversion
🔸 Details depend on abstractions	🔸 Abstractions should not depend on details

Principles

Single Responsibility Principle

🔸 Only one reason to change
🔸 Only one responsibility

Avoid God classes
