Django -> open source web development framework using python and follow Model-View-Template(MVT)

Models -> Each class(model) extends Model class from django.db -> Database table
Views -> Function that takes HttpRequest and return a HttpResponse as html page or redirect or etc.. after processing
    1. class based views -> extends View class from django.views, contains special methods for Http methods with request as parameter
    2. function based views -> request as parameter and act corresponding to http method
urls -> map each url with respective view, name_of_view.as_view() for class view
Templates -> An html page with python code for displaying data from view

MongoDB -> An open source NoSql Database
djongo -> Driver for allowing Django to use MongoDB as the database backend.

API -> Application programming interface -> intermediate btw two applications for communication btw them
How two applications will communicate?? By asking and sending data in any format(JSON, XML, etc...)

REST API -> Representational State Transfer -> set of rules or guidelines to build a web API

djangorestframework => provides necessary functions to create a restfull web service using django and python
Steps to create a rest api:
1. pip install djangorestframework
2. add rest_framework to installed_apps
3. create serialize.py file  -> convert model <-> json for transmission -> tells the rest framework what and how to serialize
4. create view to display data -> create a viewset by getting data from model and pass it to serializer
5. map urls -> rest_framework router will automate this task by passing the viewset to it
