Case study
Data Vault Foundations
Who it is for
People who have to work with a Data Vault and have never built one: analysts, engineers moving to a new warehouse, and the compliance people who must sign off on it. The goal is usable understanding, not a certificate. By the last chapter you have written the SQL and taken the compliance self-test.
The curriculum
Fourteen chapters, in the order you take them. Five are regulatory.
- Chapter 1: Ontology
- Chapter 2: Data Vault Deep Cuts
- Chapter 3: SQL SELECT
- Chapter 4: SQL JOINs
- Chapter 5: Compliance and GDPR
- Chapter 6: dbt Tools
- Chapter 7: EU Regulations
- Chapter 8: Compliance Mechanisms
- Chapter 9: AI Act and Data Vault
- Chapter 10: SQL CREATE TABLE
- Chapter 11: SQL Practice and dbt
- Chapter 12: Integration Day
- Chapter 13: Compliance Self-Test
- Chapter 14: Python Vault Runner
Exercises and feedback
More than a hundred exercises, each answered on the spot, and quests that string them into something you finish rather than a list you abandon. The progression unlocks as you go.
The regulatory track
Five of the fourteen chapters are regulatory: GDPR, EU regulations, compliance mechanisms, the AI Act, and a compliance self-test. They treat compliance as part of the data model — which satellite holds the sensitive attributes, what a deletion has to leave behind — rather than a chapter bolted on at the end. The same question, taken further, became a paper: Engineering AI Act data governance for data teams.
Gamification
The progression logic follows Yu-kai Chou's Octalysis framework; the same reading produced the Gamification Helper Tool on this site.
Design and build
Fourteen static pages that open from one chapter portal. It runs anywhere a browser runs.
I design the product and make the technical calls — architecture, stack, interactions — then direct AI coding tools that build to my spec. I review and test everything that ships.
Where it stands
Live and free. This is independent work and this site sells no Data Vault consulting. For certification and enterprise Data Vault, see Scalefree.
