In this article, we will see SOLID principles and how to implement those principles while building a software application. Robert. C. Martin (popularly known as Uncle Bob) introduced the SOLID principle. Later, Michael Feather re-orders the principle to form the acronym. It helps to implement better code design, maintainability, and extendability.

In this world of technology, meaningful and understandable software can be controlled easily. While designing the application's architecture, loose coupling between the services is necessary, meaning services should behave as a standalone application. This kind of architecture is called service-oriented architecture because, in this architecture design, we mainly focus on designing separate services and using them to make the whole application.
