New East Coast Certification Class announced, and an announcement from Centennium – I will not be attending nor teaching the certification in the Netherlands in November.

#datavault: Advanced Architecture Conference – Slides
Hello everyone, I’ve posted the slides from the Advanced Architecture Conference in Denver. Most of these slides are similar to the ones I posted a few days ago, but there is a brand new section here – that section introduces and discusses Operational Data Vault (operational data warehousing).
Column Based Data Vaults #datavault
Column based data stores have been around for a long time. This blog will talk about what you need to do to make the Data Vault successful on a column based data store. It’s quite simple really, and in the end – some parts of physical data modeling don’t matter in a column based data store.

When “Good Data” Goes Bad….
I just had a really funny experience, with good data that is… I just thought I’d pass this along.
Trashy Data Improves Profits
Really now, what is trash data? Data gone bad! You know as I do that data is an asset. What most people take for granted (or believe) is that only “good data has value.” I’m here to tell you that belief couldn’t be further from the truth.

Mathematics of Joins, Denormalization, Rows Per Block and IO
People come to me all the time complaining about the NUMBER OF JOINS in the Data Vault. I thought I might take a crack at answering this question/complaint, and provide some solid mathematical proof behind the fundamental design of the Data Vault model. I welcome your feedback (I hope you take the time to comment).
Hardcore Table Comparisons: Dimensional and Data Vault
There are a lot of comments, and questions out there about the Data Vault model, particularly from those who claim to know it and understand it. Yet some of them have a) not engaged me, nor b) gone to take the certification class. Reasons for the DV model are buried in the methodology – a lot of benefits come from using both the data modeling techniques and the methodology. That’s for another post. In this post I will try to focus JUST on the physical table structures, similarities and differences, so that the physical nature of the structures can be “compared” (so to speak).
Clash of the Titans: Post on Kimball Forum
The Data Vault Model is NOT the be-all-end-all solution to data warehousing, it IS a single evolutionary step forward, as it is a Hybrid design. If you don’t feel pain in your current implementation, then you may not be a candidate for the Data Vault model and methodology.
Upcoming Events, I’m Teaching!
Data Vault Events, certification class, Bill Inmon Conference, and new US based certification class in 2012.
A look at Inmon Approach and Data Vault
After posting the Cats and Star Schemas, I was just asked about the Inmon Approach and the Data Vault. This is a video entry regarding that subject.

Cat Continuously Smacks Head Against Star Schemas
Warning: This post is not for the faint-of-heart who are easily offended. This post is a short life-lesson about my cat, doing the same thing over and over again. And how, I’ve experienced life in Business Intelligence projects around the world – doing the same thing over and over again and yet, expecting different results.
Changing Face of “Data Warehousing”
I’ve been pondering this for years, and I’ve written about it (as have many others) over the past few years… Now I feel the urge to post about it. The term “Data Warehouse” and Data Warehousing may be old, but where we’re headed is new… Or is it?
