Ruby On Rails (RoR)

Ruby on Rails (RoR) is a cross-platform Web application framework written in Ruby. The framework was originally authored by David Heinemeier Hansson and researched and further developed by a rail core team of several individual contributors. RoR allows a programmer to develop Web applications much faster by minimizing the steps, time and verbiage involved in programming.

RoR is simply known as Rails. The initial release of RoR was in July 2004. RoR is distributed under the MIT license.

Ruby on Rails (RoR) follows the model-view-controller (MVC) approach in which the application logic isseparated from the user interface. RoR implements a popular technique called unobtrusive JavaScript to isolate the application functionality from the user Interface. Just like any other modern framework, RoR implements a “convention over configuration” approach which seeks to reduce the number of decisions that programmers need to make. RoR consists of several packages such as:

• Active Record: an architectural pattern that stores information in relational databases.
• ActiveResource: package that provides Web services.
• Action Pack: management package with control functions.
• Action Web services: Web services package.
• ActiveSupport: support management component.
• ActionMailer: Email management component.

Although RoR was originally written to run on the Mongrel Web server, it now supports most webservers and also supports database servers such as MySQL, PostgreSQL, Oracle, SQL server and DB2.
