hello everyone, apparently there are those out there in the market place who are spreading false rumors – they believe that i am only in data vault for the money. let me put these rumors to rest right now.
sadly i feel i have to address these issues, as these folks whom are spreading these false rumors are making it difficult for everyone to believe in the value proposition that data vault brings to the table. why these folks feel they have to continue making false claims, and slander my name is beyond me.
a bit of history…
i worked hard from 1990 to 2000 to build, design, engineer the data vault (model, methodology, architecture, and implementation best practices). i published countless blog articles on multiple sites over the years, and helped daniels college of business at denver university establish a masters degree program around bi and data warehousing that included data vault at it’s core (this program is apparently defunct now).
i have published two books on the subject on data vault: super charge your data warehouse, and building a scalable data warehouse with data vault 2.0 – which are available for purchase (just as any other industry trainer or thought leader) at your local bookstore, or on amazon.com for a nominal fee.
by the way, i make 5% of the profit of every book sale that occurs. so if you think i’m getting rich off of book sales, think again. michael olschimke my co-author also makes 5% of the book profit. 90% of the book profit goes to morgan kaufman (elsevier press).
my competitors (whom i am not affiliated with) are actually selling my original and old materials for their own profit and gain on amazon.com, including the original and past certification exams.
no – that is not me doing that, i am *not* affiliated with anyone else unless they are listed on:
i taught data vault modeling for free from 2001 to 2007 at tdwi us world wide conferences, along with big data, master data, data governance and a variety of other topics. until tdwi decided that “data vault conflicted with cbip (certified business intelligence professional) the certification that is highly focused on kimball star schemas. i even took the cbip exam, and passed at a mastery level.
i have presented for free, at numerous dama local chapter meetings, oracle user group meetings around the country on the basics of data vault, why and what and how, and tdwi and user group meetings across europe.if i were “in this for the money” – i would have trademarked the names, patented the methodology, architecture, and implementation standards, and i would be charging companies to license the entire process, methods, and ways of working.
sanjay pande and i are creating a new community!! we want everyone to have one place to go for all things data vault related. we are excited to announce http://datavaultalliance.com i really hope you will sign up (at this point i am just collecting your email, so that we can send you notifications when we open the doors in mid august 2018)
my questions to you (if you still believe that i am in it for just the money) are as follows: do you belong to any other professional associations? dama, tdwi, oracle user groups, pmi? they all charge yearly fees / dues. do you attend any of their conferences? their conferences also charge entrance fees (have to pay for the hotel, food and audio video somehow). do you hold any certifications? if so, was it free to get certified? no. all certifications worth anything cost money. all professional associations you belong to cost money, all conferences you attend cost money. there is nothing different about the datavaultalliance.com either – we provide value to you. instead of paying for an instructor to help you on-site (which costs a lot more than $79 usd per year), you simply pay a once a year fee, and can get answers directly from the instructors.
a short note about datavaultalliance.com – it will be a community for everyone. it will contain the following:
- free newsletters, free articles, blog posts, and videos for both business and technologists
- free subscription – once you provide your email, you will have free access to deeper articles, blog posts, videos, newsletters, and additional information
- paid membership – monthly, or yearly membership for a nominal fee (small fee / affordable) that will provide you with access to exclusive content, deeper details, and access to training classes
datavaultalliance will have two tracks: business track and technical track.
if you sign up on the web site today, you will receive discount coupons, and newsletters (free to opt out) once we open the doors.

in reality, i am a professional in the industry. just like any of you – i have to earn a living somehow, and just like these people spreading these rumors, they too are earning a living (guess what??? off of my materials, my standards, my hard-work, my ideas)… it’s a real shame that they feel they have to point the finger at me, when they are doing exactly the same thing as i am, except they are leveraging my ideas to do it.
so all that said: i earn a living from training – i love to teach people how to fish, and not fish for them. i earn a living from consulting with companies and government agencies, and assisting them in getting their data vault visions / programs / thoughts corrected and put in the right direction. beyond that? data vault itself is free, freely available, globally documented – heck it’s even described in it’s basic forms on wikipedia. i earn zero from that (which is the way it should be).
data vault is free…
the only control i maintain is over the standards themselves. why shouldn’t i maintain my own standards? after all, i built and designed the model, methodology, implementation, and architecture – and i did it for global, enterprise solutions that struggle with real-time, big data, and a whole host of other issues.
these standards must be maintained, as they have been vetted, tested, with years of effort (over 30,000 test cases from 1990 to 2001) and since then, another 10,000 test cases. all designed with the outcomes in mind of creating success in your organizations. in other words, these standards are free as well, but are built and designed to help you overcome the challenges and pitfalls that you will run into if you don’t follow them.
most of these standards are documented in the book: “building a scalable data warehouse with data vault 2.0” – available on amazon. the reason why not “all the standards” are available, is because a) it takes time to vet, clear, and articulate them in proper format for everyone to understand, b) the binding on the book was at it’s limit (698 pages max)
anyhow, i hope you enjoy the successes of data vault 2.0 by leveraging the proper standards in the model, methodology and design around the world. getting certified with cdvp2 only enriches your experience, bringing your knowledge up to date to include real-time, nosql, and a variety of specific business cases that help you in your day to day job.

there are quite a few authors that i read frequently, as well as friends that i work with in the industry.
