"Where does Django fit in"? It fits in on the server machine. A HTTP server program (like Apache or nginx) takes web page requests, and passes them onto Django. In turn, Django interprets the requests, generally running queries on the database and doing whatever processing is necessary to generate a web page. Django then throws the generated web page to the HTTP server, which then sends it back to the web browser. Django has a development server where you can request and receive pages without something like Apache or nginx. But this is not recommended in a production environment, because it is a lot slower. Django is used for generating content dynamically; but there is no gain in using development server to fetch static files (like images). > Q: There are simple websites which just serves static contents and other > site which deals with forms and data base.

All you need is your favorite HTTP server. But if you are dealing with forms and databases, then Django is very, very suitable indeed. There are classes in the framework that allow you to create forms on the fly. As for databases, there are also classes that allow you to model the database tables and run queries _without writing any SQL_. Do you really want to write your own SQL statements? I don't. You asked "are there some other modules which needs to be used?" Well, you need Python to run it; Django won't work without it. But other "modules" you may need are modules written in Python - and they can be installed as simply as running "pip install <module-name>" from the command line. One of the best things about Django is that a lot of security is built in by default. You can write something and be fairly confident that all the attack vectors have been blocked off. SQL injections? Not a problem; the model classes do all the hard work of passing queries to the database and _escaping content_. Cross Site Request Forgeries? The form classes prevent such things occurring. > Q: Is Django a substitute to CGI for dynamic web generation. > > It sounds better than bog standard CGI, where every request spawns a new process. > Q: Can i use Django for development of a full fledged website. > > > Of course you can.
