1. Django – Introduction

              Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Django makes it easier to build better web apps quickly and with less code. Django is a registered trademark of the Django Software Foundation, and is licensed under BSD License.

History of Django:

• 2003: Started by Adrian Holovaty and Simon Willison as an internal project at the Lawrence Journal-World newspaper.

• 2005: Released July 2005 and named it Django, after the jazz guitarist Django Reinhardt.

• 2005: Mature enough to handle several high-traffic sites.

• Current: Django is now an open source project with contributors across the world.

Django – Design Philosophies:

Django comes with the following design philosophies:

• Loosely Coupled: Django aims to make each element of its stack independent of the others.

• Less Coding: Less code so in turn a quick development.

• Don't Repeat Yourself (DRY): Everything should be developed only in exactly one place instead of repeating it again and again.

• Advantages of Django:
  Here are few advantages of using Django which can be listed out here:
  
  
  • Object-Relational Mapping (ORM) Support: Django provides a bridge between the data model and the database engine, and supports a large set of database systems including MySQL, SQLite3, Oracle, Postgres, etc. Django also supports NoSQL database through Django-nonrel fork. For now, the only NoSQL databases supported are MongoDB and google app engine.
  • Multilingual Support: Django supports multilingual websites through its built-in internationalization system. So you can develop your website, which would support multiple languages.
  • Framework Support: Django has built-in support for Ajax, RSS, Caching and various other frameworks.
  • Administration GUI: Django provides a nice ready-to-use user interface for administrative activities.
  • Development Environment: Django comes with a lightweight web server to facilitate end-to-end application development and testing.
  
  
  
  
  Fast Development: Django's philosophy is to do all it can to facilitate hyper-fast development.

• Clean Design: Django strictly maintains a clean design throughout its own code and makes it easy to follow best web-development practices.
