Patent pending was dropped in 2003, so please check your facts. Those articles were published in 2001/2002. If you have questions, please feel free to post them directly to me, I'd be happy to answer them. Regarding many words and little substance... if this were truly the case, then we wouldn't have many many large organizations actually using the Data Vault successfully. Including but not limited to: DOD, US Navy, US Air Force, Central Bank of Indonesia, Diamler Motors, SNS Bank, Central Bureau of Statistics, Netherlands Tax Authority, Dutch Police, Edmonton Police, JP Morgan Chase, Cendent Timeshare Resource Group, Lockheed Martin, and so on....
I'm sorry that you think there is little substance. Please feel free to read more information at: http://www.DataVaultInstitute.com, http://www.b-eye-network.com/blogs/linstedt, wikipedia, and other places like "Data Warehousing for Dummies" book, etc...
I disagree with the statement that "simply using a surrogate" suffices to track data over time. What happens if the relationships change in 3NF? What happens when you have History of History? What happens when attributes change? How fast does your IT team respond to changes, is it 30, 60 or 90 days or more for your team to incorporate the changes necessary to the data warehouse? Does your model scale to the Petabyte size warehouse? How about just 100 Terabytes?
Lots and lots of questions for you, that I'm curious how you would answer them. I have begun answering these questions, and more on the forums, blogs, and other areas of the web.
Thank-you kindly, Dan Linstedt
