Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It is best suited for developers working to tight deadlines who need to get a prototype up and running quickly. Django uses the MVT (Model View Template) structure, with the Model interfacing with the database, the View handling logic, and Templates managing the display. It provides many features out of the box like an object-relational mapper and built-in authorization tools to streamline the development process.

3. Google defines Django as
“Django is a high-level Python Web framework that
encourages rapid development and clean,
pragmatic design”
In much simple terms it is best suitable for
perfectionists with deadlines.
i.e. SOFTWARE BACKED BY DATABASE.

6. STEPS
1. Requirements planning
evaluate user’s demand.
2. User design
deciding on the design of the
user interface.
3. Rapid construction
build a prototype and
demonstrate it to the user.
4. Cutover
Convert from prototype
to final product.

7. MVT Structure
(Model View Template)
Model  database
interface
View logic for database
I/O
Template  display logic

8.  Fast  Rapid Application Development
 Secure  Helps developer avoiding
security concerns
 Scalable  Quick and flexible scaling.
 Provides both admin and client control
 Features ORM i.e. Object Relational
Mapping
 Encapsulates the code needed to
manipulate data
 Saves from SQL
 Prevents from reinventing the
wheel/hustle free development.
 Loosely Coupled

12. DJANGO is ‘LOOSELY’ COUPLED !
 Coupling in programming refers to the inter dependency of
modules.
 Thus, program efficiency is inversely proportional to coupling.
 Django is loosely coupled and thus provides better effeciency.

15. 1. Install Python from https://python.org/download/
(Since it’s a python framework Python installation is
must)
2. Install Setup tools from
https://pypi.python.org/pypi/setuptools
3. Install PIP from
https://pip.pypa.io/en/latest/installing.html
i.e. Python Package Index, works as a python manager.
4. Install Django from
https://www.djangoproject.com/download/
5. Django officially supports database
1. PostgreSQL
2. MySQL
3. SQLite

16. Common pitfalls and their solutions
Problem  Django-admin may only display text
no matter what argument is given.
This occurs due to problem with file
association in Windows
Solution Check if there is more than one
environment variable set for running
Python scripts in PATH. This usually
occurs when there is more than one
Python version installed.

17. Problem  There might be problem in
running the commands
easy_install pip and pip install
django. This happens when
connecting internet behind the
proxy.
Solution  Set environment variables for
proxy configuration in command
prompt as :-
