Ruby on Rails is a server-side web application framework under the MIT License written in Ruby. Rails is a model–view–controller framework, providing web services, web pages, and default structures for a database,.

Ruby ranks amongst the top ten programming languages predominantly because of the voguishness of Rails. While it's clear that Ruby is a more difficult programming language to master, in many ways, it is a more robust language that is better suited for creating business applications.
