User-defined functions (UDFs) in Power BI let you build reusable, automated tests for your semantic models — so you catch broken measures, duplicate rows, and faulty relationships before they reach your reports.

Concurrency and Baseline Control: Level 5 of the Stairway to Reliable Database Deployments
As database development scales across multiple contributors, concurrency becomes an inherent aspect of the process. Changes that are individually correct may still conflict when developed against a shifting baseline. This level introduces a disciplined approach to managing parallel changesets by controlling their scope, identifying overlap, and resolving conflicts through realignment. By ensuring that only one changeset retains its original baseline while others are adapted accordingly, deployments remain predictable and consistent. Once released, changesets are treated as immutable, and further evolution proceeds through new, forward-only changes.
