Persist data with SQL. An ORM is a tool, not a substitute for understanding queries.
Curated resources
Scores are LearnPath editorial opinions (clarity, cost, freshness, project density) — not an objective ranking. Every YouTube item is embedded officially after a click-to-load facade.

Twenty-eight minutes that cover what Redis is good for, the core data types and the caching patterns that actually show up in production — with clear distinctions about when not to use it.

Six hours on relational design — entities, keys, relationships, normal forms, constraints — taught with diagrams and then implemented. The resource that prevents the schema mistakes most developers make on their first real project.

Eighty-three minutes, published 2026, covering documents, queries, the aggregation pipeline and wiring Mongo into a small application with a real project. Current enough to reflect MongoDB 8-era drivers.

The longer 2019 course — four hours and twenty minutes — with more time on joins, indexing and administration than the 2023 version. Still accurate because Postgres' core semantics have not changed.

Twenty-nine minutes that finally make 1NF through 5NF click, using worked transformations of the same table rather than abstract rules. Ideal as a refresher before a design review.
