Course overview
Every dashboard, every report, every backend service eventually talks to a database — and SQL is how you talk back. It's the single most transferable skill across data analytics, data science, and backend development roles.
This course takes you from basic SELECT statements to joins, subqueries, indexing, and query optimisation, practising on real, realistically-sized datasets rather than three-row toy tables.
Why learn this?
Almost every technical interview, at every level, tests SQL somewhere. It's the one skill on this list that stays relevant no matter which specialisation you move into afterwards.
