SOLID Mastery -> Dependency Inversion Principle (DIP)

DIP IN SOLID

Welcome Everyone, Today i going to cover last my last article on SOLID principles. I have been covering these topics in a greater detail to make sure i and you both grasp these completely.

The Dependency Inversion Principle (DIP) is the fifth and final pillar of the SOLID design principles, and it addresses a common pain point in software development: tight coupling between high-level logic and low-level implementation details. If you’ve ever tried to swap out a database or modify a feature only to find that changes ripple through many parts of your code, DIP is here to help.

What is the Dependency Inversion Principle?

The Dependency Inversion Principle states that high-level modules should not depend on low-level modules; both should depend on abstractions.

Abstractions should not depend on details; details should depend on abstractions

In simpler terms, DIP proposes inserting an abstract layer between high-level policy code and low-level detail code. Instead of a high-level component directly calling a concrete implementation, both rely on a shared abstraction (such as an interface or abstract class).
