Django Models

Models define the structure of stored data, including the field types and possibly also their maximum size, default values, selection list options, help text for documentation, label text for forms, etc.

• The definition of the model is independent of the underlying database — you can choose one of several as part of your project settings.
• Django handles all the dirty work of communicating with the database for you
• It makes sense to have separate models for every object
• Models are usually defined in an application’s models.py file.
