Ruby On Rails

---

Ruby on Rails is a free web application framework that aims to increase the speed and ease with which database-driven web sites can be created and offers skeleton code frameworks (scaffolding) from the outset.

In 5 minutes, Ruby on Rails can be used to create a web-based search engine for Flickr using their public API with AJAX. It is an open source project written in the Ruby programming language and applications using the Rails framework are developed using the Model-View-Controller design paradigm:

• Ruby is a reflective, dynamic, object-oriented programming language. It combines syntax inspired by Perl with Smalltalk-like object-oriented features, and also shares some features with Python and Lisp.


• Model-view-controller (MVC) is an architectural pattern used in software engineering. In complex computer applications that present a large amount of data to the user, a developer often wishes to separate data (model) and user interface (view) concerns, so that changes to the user interface will not affect data handling, and that the data can be reorganized without changing the user interface.
  
  

  The MVC solves this problem by decoupling data access and business logic from data presentation and user interaction, by introducing an intermediate component: the controller.
