Last month we had the pleasure of hosting and assisting with another excellent Data Vault Modelling and Certification course at our OptimalBI office in Wellington. It was the biggest workshop we have ever facilitated, and we had to get creative with our office layout to fit everyone into our space.
The course was lead by Hans Hultgren, a central figure in the Data Vault universe. Hans is a Data Warehousing, Business Intelligence and Big Data educator, author, speaker, and advisor. He travels all around the world to teach his specially designed Data Vault course and advise on Data Vault implementation. Before entering the Data Vault teaching space full-time Hans spent 20 years as a professor at the University of Denver. With such tremendous teaching experience, it’s no wonder people are lining up to learn Data Vault from him!
When he is not off teaching courses around the world, he lives in Golden, Colorado, near the Genesee Academy, the place where his leading edge Data Vault training and books are brewed. Hans also spends some of his time in Sweden, where he has residency as well. Data Vault is a hot technique in Europe and his course is in high demand there. We haven’t managed to convince him to move to New Zealand yet, despite the increasing demand for courses in Australia and New Zealand. We’ll keep working on it.
Hans’s book, “Modeling the Agile Data Warehouse with Data Vault”, is available on Amazon and is a great read if this is a field you’re interested in. All course attendees get a free copy of the book, in addition to a special course book, as part of the course. In our opinion, the book portrays the Data Vault philosophy in an impressively comprehensive way, from basics through to the gritty details.
As an individual, Hans is a very pleasant person who makes a real effort to remember course attendees and connect with them. He encourages attendees to keep in touch with him through LinkedIn and Twitter even after the course. It’s also a good way to keep in touch with the Data Vault community around the world, share ideas and discuss tricky cases. We should also mention that every time Hans in town, he organises Data Vault course alumni drinks, inviting all past attendees and current participants to have a drink and network. It also gives us all a chance to enjoy the craft beer scene Wellington is well known for.
Data Vault is not a rigid approach, it develops over time and absorbs new best practice and proven solutions. That’s why Hans’s course develops all the time; the current course book is a version 38! Although core concepts stay same, Hubs, Satellites and Links are still the only tables you need, modelling and implementation techniques change over time if the better solution is found. Recent updates in the Data Vault world include – no more two-way links and no satellite on links, always add a keyed instance to the relationship. Another new trick to help with modelling is the ‘dog bone’ and ‘wishbone’ analogies. On this year’s version of the course, Hans paid more attention to the data integration and Big Data solutions. No matter the version, Hans’s course book is always well laid out and formatted, and it’s even nicer to read thanks to the inclusion of beautiful natural and urban photos Hans has taken while travelling around the world.
Hans will be back again next year for another trip into the depths of Data Vaults, and we run many Business Intelligence courses throughout the year, so if you’re interested in coming along and learning the latest in this area make sure to follow us for all the latest updates.
