In ASP.NET MVC application MVC gives use 3 part Controller, Model & View. But if we want to separate the  Controller, Model & View as our application Module based we can also implement this using AreaRegistration. Consider i want to use PIS module with seperated Controller, Model & View. i have to add a user define class, i just named it PISAreaRegistration.

  public class PISAreaRegistration : AreaRegistration  
   {  
     public override string AreaName  
     {  
       get  
       {  
         return "PIS";  
       }  
     }  
     public override void RegisterArea(AreaRegistrationContext context)  
     {  
       context.MapRoute(  
         "PIS_default",  
         "PIS/{controller}/{action}/{id}",  
         new { action = "Index", id = UrlParameter.Optional }  
       );  
     }  
   }  

if you want to add more module like PIS then you have do the all process as PIS done.
