About ASP.NET MVC Applications

The Model View Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller. The ASP.NET MVC framework provides an alternative to the ASP.NET Web-forms pattern for creating MVC-based Web applications. The ASP.NET MVC framework is a lightweight, highly testable presentation framework that (as with Web-forms-based applications) is integrated with existing ASP.NET features, such as master pages and membership-based authentication. The MVC framework is defined in the System.Web.Mvc namespace and is a fundamental, supported part of the System.Web namespace.

The MVC pattern helps you to create applications that separate the different aspects of the application (input logic, business logic, and UI logic), while providing a loose coupling between these elements. The pattern specifies where each kind of logic should exist in the application. The UI logic belongs in the view. Input logic belongs in the controller. Business logic belongs in the model. This separation helps you manage complexity when you build an application, because it enables you to focus on one aspect of the implementation at a time. For example, you can focus on the view without depending on the business logic. You can read more about ASP.NET MVC Applications here.

JQuery

JQuery is an extensible javascript library designed to make life easier for web developers. It provides cross-browser wrappers for calling functions and accessing css attributes, taking the 'pain-in-the-but-ness' out of things like having to call document.getElementById('id') 30 times. Instead it's as simple as $('#id'). Check out the documentation for more information on the main JQuery page at the JQuery Main Page.
