The app is where the data starts and SQL Server is where it’s kept. That SQL Server data supports Chelten House’s Tableau reporting.
Why that order matters for any plant
Reports are only as consistent as the records underneath them. When categories such as planned vs unplanned, and the cause of each stop, are captured as structured fields at entry, a reporting tool can group and total them directly, without someone cleaning up free text first. Capture at the source, store in a database, report from the database: that’s the general pattern we recommend.

Our guide to a SQL Server schema for downtime and OEE data lays out a general pattern Tableau can report on: production runs, stop events, reason codes and shifts. It’s our recommended starting point for any plant, not Chelten House’s schema.
