The Analyst Turns Data Training Into Office Hours From Hell
A browser-based practice environment for SQL, Python, analytical judgment, and professional handoffs, staged inside a fictional company with messy operational data.
Field notes
The training environment uses one connected fictional company rather than a collection of unrelated classroom datasets. Learners move through customer care, commercial data transition, experimentation, and connected-device reliability scenarios while working against 16 schemas, 96 tables, and 16.5 million synthetic rows. The stated workflow combines local SQL and Python analysis with a portable submission containing queries, notes, captured outputs, versions, and hashes.
