SOLID Principles

Topics: Design Pattern

SOLID is a set of five object-oriented class-design principles discussed by Robert C. Martin in Principles of OOD.

There are five SOLID principles:

• Single Responsibility Principle
• Open-Closed Principle
• Liskov Substitution Principle
• Interface Segregation Principle
• Dependency Inversion Principle

Martin categorises them as principles of class design. They’re intended to make software designs more understandable, flexible and maintainable.
