A collection of good libraries, less works but achieve better results and faster.

There are lots of nice tools, classes and methods to makedevelopment easier.


Ruby is:• A High Level Programming Language• Originated in Japan and Rapidly Gaining Mindshare in US and Europe.


Why Ruby ?• Easy to learn• Open source• Very easy to extend• Truly Object-Oriented• Less Coding with fewer bugs


Rails is• A web-application framework written in Ruby by David Heinemeier Hansson.• Model-View-Controller


Model (ActiveRecord ) :Maintains the relationship between Object and Database and handles validation, association, transactions, and more.


View ( ActionView )A presentation of data in a particular format, triggered by a controller's decision to present the data.


Controller ( ActionController ): is the logical center of your application. It coordinates the interaction between the user, the views, and the model.


A Pictorial Diagram of Ruby on Rails Framework:


This can be created by using sample helper command C:\InstantRails\rails_apps>rails demoThen you will find a directory structure as follow:


demo/ ..../app ......../controller ......../helpers ......../models ......../views ............../layouts ..../components ..../config ..../db..../doc ..../lib



Go to http://rubyforge.org/projects/instantrails/

1. Instant Rails 2.02. Instant Rails 1.73. Instant Rails 1.54. Instant Rails 1.45. Instant Rails 1.3a


1. Unzip Instant Rails on any hard drive2. Start server Apache and MySQL


Go to command prompt by using helper command as follow:C:\InstantRails>use_ruby


Rails will try to use Mongrel and lighttpd if they are installed, otherwise Rails will use WEBBrick, the webserver that ships with ruby.


Windows users are encouraged to Start with Mongrel because it is a Ruby-based webserver that is suitable for development and deployment of Rails applications.
