Ruby on Rails is an agile web application framework that uses the Ruby programming language. It incorporates the Model-View-Controller architectural pattern, using conventions over configurations and Don't Repeat Yourself principles. Rails emphasizes convention and abstraction to minimize configuration and promote rapid development of maintainable web applications.
