Where do I find a realistic dataset for a SQL or analytics course, with an answer key?
Describe the business and what students should discover, for example a restaurant chain where one branch's food cost creeps up after a supplier change, and Misata Studio builds linked tables with that finding planted at the size you ask, plus an answer key saying where it shows and how to find it. Because the same recipe with a new seed gives a different but equally valid dataset, each cohort can get its own copy and last year's answers do not carry over.
Best for: Instructors, bootcamps, course authors and anyone setting take-home data tasks.Updated 6 Oct 2026
A restaurant chain with 12 branches over two years: menus, orders, order items, suppliers and deliveries. After a supplier change in March 2025, one branch's food cost rises from 28% to 34% of sales. Include a few duplicate orders and missing delivery dates for students to clean.
- Findings planted at the size you choose
- An answer key with the query for each
- Dirty data on purpose: duplicates, gaps, typos
- A new variant per cohort from the same recipe
Why it holds up
Gradeable
Every planted finding is listed with its numbers, so marking checks an answer against the truth.
Realistic enough to teach with
Prices, quantities and dates fit the business, and the tables join the way real systems do.
No copied answers
A new seed gives each cohort its own data, so solutions from earlier years do not fit.
