What is Ruby on Rails? 

Ruby on Rails ('RoR' or 'Rails') is an open source framework scripting language based on Ruby.  Scripting languages use a program that runs on the web server to 'translate' each time the script runs. 

Rails runs best on Apache and Lighttpd web servers, but can run on any server that supports mod ruby (Apache), CGI, SCGI or FastCGI.

A big plus is that Rails helps save time when coding web applications that are backed by databases.  Rails can automate much of the development process.

Rails is handled by an object-relational mapping (ORM) layer called Active Record.  This layer will enable you to present the data from the database rows as objects and decorate the objects with business logic methods.

You are probably saying at this point, "What the heck??"  It's easy.  The Active Record is a layer supplied with Rails and it closely follows ORM model of tables map to classes, rows map to objects and columns map to object attributes.  Rails Active Records binds between the tables in a relational database and the Ruby code that manipulates database records.  Each Active Record object uses the Create, Read, Update and Delete (CRUD) methods.
