The Bridge Key Is a Hash of a Path

BimlFlex derives a bridge table's key from the traversal itself: the hub key plus every link key, hashed like any other Data Vault key. Missing legs get the zero key, and the generated load can only add rows, never change them.

The MERGE Behind SCDs

Stop hand-writing slowly-changing-dimension logic. BimlFlex generates the Type 1 and Type 2 MERGE behind your dimensions, including date ranges, current flags, and change detection, on every target.

What a Satellite Really Is

Cut through Data Vault satellite confusion. Learn the three satellite types, plus Multi-Active and effectivity as column modes, and how BimlFlex automates each in your model.
