.. glossary::
field
An attribute on a :term:`model`; a given field usually maps directly to
a single database column.
See :doc:`/topics/db/models`.
generic view
A higher-order :term:`view` function that provides an abstract/generic
implementation of a common idiom or pattern found in view development.
See :doc:`/ref/generic-views`.
model
Models store your application's data.
See :doc:`/topics/db/models`.
MTV
See :ref:`mtv`.
MVC
`Model-view-controller`__; a software pattern. Django :ref:`follows MVC
to some extent <mtv>`.
__ http://en.wikipedia.org/wiki/Model-view-controller
project
A Python package -- i.e. a directory of code -- that contains all the
settings for an instance of Django. This would include database
configuration, Django-specific options and application-specific
settings.
property
Also known as "managed attributes", and a feature of Python since
version 2.2. From `the property documentation`__:
Properties are a neat way to implement attributes whose usage
resembles attribute access, but whose implementation uses method
calls. [...] You
could only do this by overriding ``__getattr__`` and
``__setattr__``; but overriding ``__setattr__`` slows down all
attribute assignments considerably, and overriding ``__getattr__``
is always a bit tricky to get right. Properties let you do this
painlessly, without having to override ``__getattr__`` or
``__setattr__``.

queryset
An object representing some set of rows to be fetched from the database.
See :doc:`/topics/db/queries`.
slug
A short label for something, containing only letters, numbers,
underscores or hyphens. They're generally used in URLs. For
example, in a typical blog entry URL:
.. parsed-literal::
http://www.djangoproject.com/weblog/2008/apr/12/**spring**/
the last bit (``spring``) is the slug.
template
A chunk of text that acts as formatting for representing data. A
template helps to abstract the presentation of data from the data
itself.
See :doc:`/topics/templates`.
view
A function responsible for rending a page.
