#datavault – Paper on Conceptual Data Vault
This article was written by a couple of authors and submitted to a conference that happened recently. It walks through some of the conceptual modeling around Data Vault, as well as taking a look at Anchor Modeling, and common approaches. It is really well written, and worth a read if you have the desire.
Column Based Data Vaults #datavault

Dynamic Data Modeling, Auto-Adaptation
I’ve long held a belief that the Data Vault modeling style ushered in a new era, that being one where we have the power to dynamically accept and automatically absorb new data elements.
