Versioning data in Django

Joseph Victor Zammit 09:45 stage 🎤

What does “versioning” mean? It means tracking the evolution of a specific record in our database. This talk is about ways to version data in a Django project. The aim is to create a balance between two, sometimes opposing goals. First goal is to have an easy-to-understand data model for product and engineering. The second is for our code to make efficient use of the database.

Example scenario:

• Your company sells widgets. We track orders in the Order model and customers in the Customer model.
• Management uses a report to show locations for orders delivered for customers.
• A customer with past orders wants to update their address. How to handle this without breaking the report just described?
• What performance considerations come into play?
• What does the Django ecosystem offer? Any alternatives? And why?

About Joseph

I’m Joseph. Or “Joe” in short. I am in software engineering since the ‘00s. Working professionally since ‘06.

Most of the time my roles were “backend”. Where working with data and relational databases is a key part of backend.

From ‘08 onwards I worked a lot with Python. And the framework I worked with most is Django.
