Data Modeling & Production Failures

Analysis of production monitoring in tabular data systems reveals pitfalls when implementing custom calendars within Power BI and Fabric models, despite feature availability since September 2025. This complexity arises because standard MLOps retraining schedules often fail in production environments, as observed when fitting the Ebbinghaus curve to 555,000 fraud transactions yielded a poor R² value of $-0.31$, suggesting models experience "shock" rather than simple forgetting leading to schedule failure.
