What are Django migrations?

Django comes with a tool called migrations which is responsible for creating, updating and deleting tables and columns in your database. It reads changes made to the models.py file inside an app, and translates those changes to the database when python manage.py makemigrationsand python manage.py migrate are called.

makemigrations is a kind of staging area for migrations, and migrate applies staged changes to the database.

It also acts as a kind of version control for your database, as each migration made is automatically logged.
