SOLID

Dependancy Inversion Principle

High-Level Modules Should Not Depend on Low-Level Modules. Both Should Depend on Abstractions:

• High-level modules (which contain complex logic) and low-level modules (which perform detailed operations) should both depend on abstractions (interfaces or abstract classes).

Abstractions Should Not Depend on Details. Details Should Depend on Abstractions:

• The concrete implementation details should depend on abstract layers, not the other way around.

SOLID Principles

There are five SOLID principles:

• Single Responsibility Principle (SRP)

• Open Closed Principle (OCP)

• Liskov Substitution Principle (LSP)

• Interface Segregation Principle (ISP)

• Dependency Inversion Principle (DIP)
