JSF - Architecture
 
JSF technology is a framework for developing, building server side 
User Interface Components and using them in a web application. 
JSF technology is based on the Model View Controller (MVC) 
architecture for separating logic from presentation. 

What is MVC Design Pattern? 

MVC design pattern designs an application using three separate modules: 



Module          Description 

Model          Carries Data and login 

View          Shows User Interface 

Controller  Handles processing of an application. 

Purpose of MVC design pattern is to separate model and 
presentation to enable developers to set focus on their 
core skills and collaborate more clearly. 

Web Designers have to concentrate only on view layer rather 
than model and controller layer. Developers can change the 
code for model and typically need not to change view layer. 
Controllers are used to process user actions. In this process 
layer model and views may be changed.
