Interactive Database Management Systems course Relata
A full DBMS course on a real SQL engine: ER modelling, the relational model and algebra, normalization, SQL with the lab experiments, then transactions and concurrency. Every query you write really runs.

- ER modelling
- Relational algebra
- Normalization
- SQL & transactions
Every scene in Relata follows the same pattern: a plain sentence saying what the idea is, a working model the student controls, a real example, then a “your turn” step.
The free preview opens the first 3 scenes in your browser. The full course comes with your college’s TwiddleLabs subscription: teachers use it in the browser, and students get it in the TwiddleLabs app on their phone and laptop, working offline.
