Learn SQL the way analysts actually use it - to answer real business questions. 102 hands-on tasks across 4 skill tiers, real Postgres syntax, instant feedback. Iron Query teaches SQL the way working data analysts actually use it - not abstract syntax drills, but real queries written to answer real business questions. Every task starts with a question a stakeholder might actually ask - "which retention offers are actually working?", "what's our net revenue after refunds?", "who are our highest-value customers by plan?" - and you write the SQL to answer it, against a real relational dataset (customers, subscriptions, invoices, campaigns, and more). 102 HANDS-ON TASKS, FOUR TIERS • Jr. Analyst - filtering, aggregation, single-table queries • Analyst - joins, date bucketing, HAVING • Sr. Analyst - window functions, gaps-and-islands, cohort analysis • Lead Analyst - multi-CTE queries and the advanced patterns real analysts rely on daily Each task includes a business-style prompt, hints if you get stuck, and an instant correctness check against a validated reference answer - so you always know whether your query actually solved the problem, not just whether it ran without errors. WRITE POSTGRES, RUN NATIVE Iron Query runs on a fast, embedded database, with a translation layer that converts common PostgreSQL syntax automatically - so the SQL you practice here is the SQL you'd write in a real analytics job. A built-in reference (Help → Iron Query Help) documents exactly what works as-is, what's translated, and what isn't supported, so there's never any guesswork about the dialect you're learning. BUILT FOR THE MAC A genuinely native macOS app - fast, offline, no browser tab, no account required, nothing sent anywhere. Try every tier free for 7 days, then unlock the full app with a single one-time purchase. No subscription, no ads, no in-app upsells after that. Whether you're breaking into data analytics, prepping for SQL interviews, or just want sharper query instincts for your current job, Iron Query is built to get you there by doing the actual work - one business question at a time.
