What you’ll learn

Write serious SQL
Joins, aggregates, CTEs, and window functions, without reaching for the ORM every time.
Design a schema that lasts
Normalise sensibly, use constraints as guarantees, and pick the right data types.
Make queries fast
Read a query plan and add the index that plan is asking for.
Operate it safely
Transactions, migrations, backups, and pooling — the parts that matter at 3am.
