PostgreSQL Crash Course for Django - Free Full-stack Course

Part of the Free Full-stack course: Welcome to the Free Full-stack Course In this course, we will be using Python as the programming language for our backend to deliver REST APIs. The REST APIs will be developed on top of Django which is a backend/website framework that sits on top of Python. And we will also use DRF (Django REST Framework) to actually deliver our APIs on top of Django. PostgreSQL is the world’s most advanced open-source relational database. Even though Django manages the database and models and relationships for us when hooked to any database management system such as PostgreSQL or MySQL, it is still beneficial to know the basics of PostgreSQL. In this chapter we will learn the basics of PostgreSQL.
