This poster displays the most important rules of the Data Vault modelling method version 1.0.9 on one A3-size cheat sheet. I decided to not add personal interpretation and keep the sheet as close to the original specs as possible.
You can find the rules that were used for this poster on the website of Dan Linstedt.

A version where the Colors of the Data Vault have been used, is available as well:
