SOLID stands for

Single Responsibility Principle - A class should have one, and only one, reason to change

Open Closed Principle - You should be able to extend a classes behavior, without modifying it.

Liskov Substitution Principle - Derived classes must be substitutable for their base classes.

Interface  Segregation Principle - Make fine grained interfaces that are client specific.

Dependency Inversion Principle - Depend on abstractions, not on concretions.
