Get Certified! #DataVault 2.0 Certification in the US

Quick update – if you have been waiting to get your Data Vault 2.0 certification there are three sessions coming in the new few months right in the USA.  If you already know you want to do that, just skip down to the links and sign up!

Why Data Vault?

The Data Vault 2.0 architecture gives you an entire systems based approach to developing a true enterprise data warehouse and analytics architecture. It is very structured, pattern based, and highly repeatable. In Data Vault, each component does it’s duty, and does it well. The engineering components are generally relegated to automation tools (because it is pattern based), so human effort is not wasted in the mundane and can be used in more interesting, intelligent and thinking tasks. It’s a much better use of intelligent beings as well as machines.

Separating the concerns makes design and development not just easy, but fast.

As a side effect projects using Data Vault 2.0 have always saved a lot of money and have been extremely successful with their predictable goals. Plus they are very resilient so they tend to stay in use for years to come with little or no re-engineering! One of my systems has been running for 14 years now – and was even successfully re-platformed in that time.

How do you get in on this innovative approach?

If you want to learn more (and why wouldn’t you?), there are many upcoming opportunities across the world to get more information about Data Vault 2.0 (just check Twitter or LinkedIn – look for #DataVault). If you understand it, and you want to use it to leverage your own successes, you can even get certified (That comes with a responsibility though).

Here’s a list of upcoming opportunities to get DV 2.0 certified in the US:

1. Sep 19-21, Chicago, IL – http://www.performanceg2.com/agile-bi-datavault-training/

2. Oct 2-4, New York City, NY – http://www.scalefree.com/2017/03/30/data-vault-2-0-boot-camp-and-certification-new-york-oct-2017/

Topic 2: Agile Methods and Data Warehousing: How to Deliver Faster

Topic 3: Agile Data Engineering: Introduction to Data Vault Data Modeling

So if you are in the St. Louis area, or fancy a trip to the Gateway to the West,  please join me there on May 2nd.

Special Discount for Data Warrior fans!

The organizers were kind enough to offer my followers a 50% discount. Wow!

Data Vault Modeling and Snowflake Elastic Data Warehouse

Since I have joined Snowflake, I have been asked multiple times what data warehouse modeling approach does Snowflake support best. Well, the cool thing is that we support multiple data modeling approaches equally.

Turns out we have a few customers who have existing data warehouses built using a particular approach known as the Data Vault modeling approach (which my readers no well by now) and they have decided to move into Snowflake (yeah!).

So the conversation often goes like this:

Customer: “Can you do Data Vault on Snowflake?”

Me: “Yes you can! Why do you ask?”

Customer: “Well, your name is “snowflake” so we thought that might mean you only support snowflake-type schemas.”

Me: “Well, yes I can see your confusion in that case, but the name has nothing to do with data warehouse design really. In fact, we support any type of relational design, including Data Vault.”

See the rest of the post here:

Keep on Modeling!

P.S. Next week I will be in Grapevine, Texas at the Gartner BI & Analytics Summit. Snowflake has a booth there. Come by and say “howdy!”

Data Vault and the Oracle Reference Architecture

Thanks to Mark Rittman and Twitter, I found out just before RMOUG that Oracle had published a new reference architecture.  It used to be called the Data Warehouse Reference Architecture, now it is called the Information Management Reference Architecture.

Oracle Information Management Ref Architecture

Oracle updated the architecture to allow for unstructured and big data to fit into the picture.

In my talks about Data Vault over the last few years I have been referring to the Foundation Layer of the architecture as the place where Data Vault fits. The new version of the architecture actual fits the definition of the Data Vault even better.

Now the Foundation Layer is defined as “Immutable Enterprise Data with Full History”.

If that is not the definition of Data Vault, I don’t know what is!

Immutable – does not change. Data Vault is insert only, no update – ever.

Enterprise Data – well duh! That pretty well fits any real data warehouse architecture. The model covers an enterprise view of the data not just a departmental views (like a data mart).

Full History – tracks data changes over time. That is one of the keys to the data Vault approach. We track all the data change history in Satellites so we can always refer to a view of the data at any point in time  That allows us to build (or re-build) dependent data marts whenever we need or whenever the business changes the rules.

So it is possible to do a Data Vault approach and be compliant with Oracle’s reference architecture.

Guess Dan was just a bit ahead of the game…
