2.What is the relationship of AJAX to JQuery and the lightweight web 2.0 javascript framework called MooTools within the enterprises software architecture?
Answer:- JQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way to write JavaScript.
      MooTools is a compact, modular, Object-Oriented  JavaScript framework designed for the intermediate to advanced JavaScript developer. It allows you to write powerful, flexible, and cross-browser code with its elegant, well documented, and coherent API.

3.What are the similarities between the object-oriented development using model-view-controller(MVC) in Rub on Rails 2.0. And action script 2.0(Flash animations)?
Answer:-
Model–View–Controller (MVC) is a software architecture, currently considered as an architectural pattern used in software engineering.The Model View Controller principle divides the work of an application into three separate but closely cooperative subsystems.
     The close simliraties MVC in Ruby on Rail 2.0 and Action Script 2.0 is both of them are used for  object-oriented development using MVC, however Ruby on Rails is for Website and application development while the ActionScript is dedicated for a specific environment - Flash animations.

4.What does it mean to develop RESTful practices into our web application?
Answer:-
The REST  stand for Representational State Transfer. architectural style for web applications was first put forward by Roy Thomas Fielding  in 2000, but in its essence it's a rediscovery of the merits of the good old HTT  protocol. JSF applications, though, normally don't conform to the HTTP  specification at all.

The basic principles of the HTTP are:

   1. HTTP is stateless.
   2. Each resource
   3.Resources are being accessed via specific verbs, each of which designates the type of the requested interaction with the resource:
         1.GET for displaying a resource
         2.POST for creating a resource
         3. PUT for modifying a resource
         4.DELETE for deleting a resource
   4.The resources can be requested in specific content types, as needed on the client.

RESTful web applications conform to these principles, it guaranteeing uniform access to resources regardless of their location, enabling easy integration and loose coupling between applications. Building on that, RESTful web applications make it easy to provide device-specific responses and search engine optimized URLs. "weba"
