Data Vault is a proven methodology for building scalable, auditable data platforms. I consider myself a fundamental advocate of Data Vault – its concepts of hubs, satellites, and links provide a solid foundation for traceability and parallelization.

However, in real-world projects, I often experienced that the full methodology was too heavy for organizations to adopt consistently. Out of this need, I developed a Lean Data Vault approach: rooted in the principles of Data Vault, but simplified to focus on what truly matters – data quality, flexibility, and speed of delivery.
