Ruby on Rails is a popular web application framework for building database-backed web applications. It uses the Ruby programming language along with gems, a Gemfile, and the asset pipeline to manage web application assets and dependencies. Rails emphasizes conventions over configuration, making it well-suited for rapid prototyping and development of web applications.
