Rails uses the Model-View-Controller (MVC) architecture just like many other contemporary web frameworks for organizing application programming. Rails is remarkable for its widespread use of the JavaScript libraries Prototype and Script.aculo.us that is significantly used for for Ajax and its graphical interface. And because of Rails’ “out of the box” scaffolding, it can promptly generate most of the models and views necessary for a basic website. Rails has useful development tools built in or already installed like the WEBrick web server and the Rake build system. Rails also originally supported lightweight SOAP for web services and it was later replaced by RESTful web services as it significantly altered to version 1.2.
