Django is a back-end server side web framework. Django is free, open source and written in Python. Django makes it easier to build web pages using Python.

Django follows the MVT design pattern (Model View Template).

• Model - The data you want to present, usually data from a database.
• View - A request handler that returns the relevant template and content - based on the request from the user.
• Template - A text file (like an HTML file) containing the layout of the web page, with logic on how to display the data.

The model provides data from the database. In Django, the data is delivered as an Object Relational Mapping (ORM), which is a technique designed to make it easier to work with databases. The most common way to extract data from a database is SQL. One problem with SQL is that you have to have a pretty good understanding of the database structure to be able to work with it. Django, with ORM, makes it easier to communicate with the database, without having to write complex SQL statements.

• The models are usually located in a file called models.py.

A view is a function or method that takes http requests as arguments, imports the relevant model(s), and finds out what data to send to the template, and returns the final result.

• The views are usually located in a file called views.py.

A template is a file where you describe how the result should be represented.

• Templates are often .html files, with HTML code describing the layout of a web page, but it can also be in other file formats to present other results, but we will concentrate on .html files.
