Important Terms
===============

This page covers important terms used in the documentation and Werkzeug
itself.


Response Object
---------------

For Werkzeug, a response object is an object that works like a WSGI
application but does not do any request processing.  Usually you have a view
function or controller method that processes the request and assambles a
response object.

A response object is *not* necessarily the `BaseResponse` object or a subclass
thereof.


View Function
-------------

Often people speak of MVC (Model, View, Controller) when developing web
applications.  However, the Django framework coined MTV (Model, Template,
View) which basically means the same but reduces the concept to the data
model, a function that processes data from the request and the database and
renders a template.

Werkzeug itself does not tell you how you should develop applications, but the
documentation often speaks of view functions that work roughly the same.  The
idea of a view function is that it's called with a request object (and
optionally some parameters from an URL rule) and returns a response object.
