ROR- Ruby on Rails is a full-fledged cross platform open source web framework that is applicable both on front-end and back-end design.
Ever since writing for web applications has been practised, there have been discovered a writing framework to help the web developer as most of the web applications are developed using multiple technologies at once. This makes the work of a developer more complex and time taking.
The web developers need to understand and keep in control various environments and languages which is not at all easy.
To help overcome the complex process, various simple frameworks have been developed including ROR which work on MVC pattern.
Instead of using different frameworks, the rail layers make it easy to work with by fitting seamlessly into the rail layers. The whole framework is written in Ruby language.
