This is the poster from 2010 that displays on one A3-size cheat sheet the most important rules of the Data Vault modelling method version 1.0.8.
You can find the rules that were used for this poster on the website of Dan Linstedt.
**Update**: Please note that the current version is version 1.0.9. This version is kept for archival and to amuse data archaeologists 🙂
