This framework is a powerful back-end programming tool for websites, offered as open-source and free of charge. It allows developers to craft the server-side components of websites and web applications with remarkable efficiency using the Ruby programming language. Ruby on Rails, often referred to simply as Rails or RoR, was introduced nine years after the creation of Ruby by David Heinemeier Hansson, a fascinating figure in the tech world with an impressive array of accomplishments.

Ruby on Rails is built on the MVC (Model-View-Controller) architecture, which neatly separates the various layers of an application. One of the standout advantages of this framework is its ability to seamlessly integrate with standard web structures, such as JSON files, XML formats, and popular front-end technologies like HTML, CSS, and JavaScript. This ensures a smooth and efficient development process for both the backend and frontend, giving developers the tools to create dynamic, robust web applications.
