The Ruby programming language is used to create the web application development framework known as Rails, hence the name Ruby on Rails. It is an open-source framework that includes everything needed to create database-backed web applications according to the MVC pattern. Your application is broken up into three layers with MVC: Model, View, and Controller, each with a particular role. RoR simplifies the process of developing web applications by accomplishing more while requiring less code to be written than many other languages and frameworks. Additionally, experienced Rails developers claim that it enhances the enjoyment of web application development.
