Web Application • How is it different from static web pages. • Three tiers: Presentation, application and storage. • Request response cycle. • Finally browser expects an html document which the server must provide.

2. About Django • Web Application framework that supports rapid application development. • DRY principle. • Code reusability and Pluggability. • Has an ORM. • Provides a web server for development. • Provides admin for CRUD. • And once done with basic work, it supports advanced things like Feeds, sitemap, caching and what not. Start writing code • startproject • runserver and show default django page • syncdb • Enable the admin • CRUD on User model • Poll and Choice model and Queryset api • Basic views and urls • Use url and reverse instead of hardcoding.
