Description
The SOLID principles are fundamental to designing effective, maintainable, object-oriented systems. Whether you've only just begun writing software or have been doing so for years, these principles, when used appropriately, can improve the encapsulation and coupling of your application, making it more malleable and testable in the face of changing requirements.
