What is versioning of extraction logic?

< 1 min read

Versioning of extraction logic means maintaining tracked versions of queries and transformations over time.
We stored Power Query scripts and SQL views in Git repository.
Whenever logic changed, a new version was committed with comments.
In my project, discount calculation logic changed based on business rules.
We created v2 extraction while keeping v1 for rollback safety.
If refresh failed, we quickly reverted to previous working version.
Version history helped audit when and why data changed.
Multiple environments like Dev, UAT, and Prod used controlled deployments.
This prevented unexpected report impact after modifications.
So versioning ensures traceability, stability, and safe updates in pipelines.
