Visualforce Pages with Apex Controllers

Visualforce is a component-based user interface framework for the Force.com platform. Visualforce allows you to build sophisticated user interfaces by providing a view framework that includes a tag-based markup language similar to HTML, a library of reusable components that can be extended, and an Apex-based controller model. Visualforce supports the Model-View-Controller (MVC) style of user interface design, and is highly flexible.

Visualforce includes standard controllers for every sObject available in your organization, which lets you create Visualforce pages that handle common features without writing any code beyond the Visualforce itself. For highly customized applications, Visualforce allows you to extend or replace the standard controller with your own Apex code. You can make Visualforce applications available only within your company, or publish them on the Web.

In this tutorial, you will use Visualforce to create a simple store front page. You’ll start with a simple product listing page that does not use Apex as a quick introduction to Visualforce. Then you’ll add a few features, like a simple shopping cart, to see how Visualforce connects to a controller written in Apex.
