As of today, I am certified as Anchor Modeler. My thanks go to Lars Rönnbäck (UpToChange.com), the best teacher you could have, as well as Juan-José van der Linden for inviting me and to Essent for hosting the course.
While the community of Anchor Modelers is still quite small, it will likely expand as the concurrent-reliance-temporal model is extremely interesting. The notion of positors and reliance combined with the positing and changing time is quite advanced. I’m looking forward to combining this with Martijn Evers’ notions about timeline choices with respect to Consistency/Accuracy/Availability.
Dear readers, on june 6th I held a keynote presentation in front of 300 people, summarizing the state of DWH modeling. The conference proceedings of the day are available at BI-Podium .
My own presentation is available here as well: Next Generation DWH Modeling 2013 conference keynote speech
The Anchor Modeling folks also wrote a summary: Next Generation DWH Modeling
Anchor Modeling is a new method of modeling a domain in a database. The method splits up all the attributes in their own table. This seems complex, but this actually simplifies maintenance. Furthermore, the method is flexible, quite resilient to change over time, does not need updates and is highly scalable.
These are good properties for a data warehouse model. In the article I explain how Anchor Modeling works and why you should at least take a look at it.
The article appeared in november 2009 in Database Magazine, Dutch magazine for database professionals. However, the magazine is now defunct and superseded by Business Information Magazine.
