Components of ASP.NET MVC3/MVC4


Models

These are the classes that represent the domain you are interested in.

With ASP.NET MVC, this is most likely a Data Access Layer of some kind
using a tool like Entity Framework or NHibernate combined with custom
code containing domain
-
specific logic



View

This is a template to dynamically generate HTML


Controller

This is a special class that manages the relationship between the View and
Model.



Model


The word
model in software development is overloaded to
cover hundreds of different concepts.


You have maturity models, design models, threat models,
and process models. It’s rare to sit through a
development meeting without talking about a model of
one type or another.


Even when you scope the term “model” to the context of
the MVC design pattern, you can still debate the merits of
having a business
-
oriented model object versus a view
-
specific model object

Crafting Model class


public class Album


{


public virtual
int

AlbumId

{ get; set; }


public virtual
int

GenreId

{ get; set; }


public virtual
int

ArtistId

{ get; set; }


public virtual string Title { get; set; }


public virtual decimal Price { get; set; }


public virtual string
AlbumArtUrl

{ get; set; }


public virtual Genre
Genre

{ get; set; }


public virtual Artist
Artist

{ get; set; }


}

What Is Scaffolding?


Scaffolding in ASP.NET MVC can generate the boilerplate code
you need for create, read, update, and

delete (CRUD)
functionality in an application. The scaffolding templates
can examine the type definition for a model (such as the
Album class you’ve created), and then generate a
controller and the controller’s associated views. The
scaffolding knows how to name controllers, how to name
views, what code needs to go in each component, and
also knows where to place all these pieces in the project
for the application to work.
