A further-education college. Enrolment states — enrolled, deferred, withdrawn, completed — become a completion rate filed with a funder. The records also carry dates of birth, addresses and the hardship and disability flags that decide funding, so a copy outside production is not something anyone is allowed to have. You still have to change the models.
A monthly return, rebuilt nightly, and the reason those two are different.
Practice studio
Run the review to check your architecture against this scenario — a valid DAG, a trigger for the freshness SLA, a transform stage, a quality gate before publish, and a failure path — then defend it in a short interview.
This scenario runs a full workspace — editor, canvas and results side by side. It needs a laptop or desktop to be usable. Open this page on a bigger screen to start building.
