MCV4 have new feature is WEB API. CRUD stands
for "Create, Read, Update, and Delete," which are the four basic database
operations. Many HTTP services also model CRUD operations through REST or
REST-like APIs.

The four main HTTP methods (GET, PUT, POST, and
DELTETE) can be mapped to CRUD operations as follows:
-
GET retrieves the representation of the
resource at a specified URI. GET should have no side effects on the server.
-
PUT updates a resource at a specified URI. PUT
can also be used to create a new resource at a specified URI, if the server
allows clients to specify new URIs. For this tutorial, the API will not
support creation through PUT.
-
POST creates a new resource. The server
assigns the URI for the new object and returns this URI as part of the
response message.
-
DELETE deletes a resource at a specified URI.
