Module 5: Data Architecture

1 min read·25 Oct 2026

What you need first

Module 4, or at least its lab (the Module 5 lab rebuilds Modules 1 to 4 if missing).
Module 3 lesson 3 (embedding cost and vector storage) and Module 1 lesson 2 (retries and idempotency).
Python functions, dictionaries and a little SQL.
A Google account for Colab and Drive. No lesson, lab or incident file calls a model, so no key is needed.

This course is bought on its own, once, and stays readable afterwards, including the parts added to it later.
