Data Vault

A modeling method for agile, auditable warehouses that separates business keys (hubs), relationships (links) and descriptive history (satellites).

Definition

Data Vault 2.0, created by Dan Linstedt, is insert-only, captures full history with load dates and record sources, and supports parallel loading using hash keys. A raw vault is usually followed by a business vault and dimensional marts for consumption.

Exam tip

Data Vault is built for auditability and change; users typically query star schemas built on top of it.
