OOW is just around the corner

Yes it is indeed time for Oracle Open World. Unfortunately I will not be there speaking myself this year, but do not despair my friends, there is still plenty of goodness from the community such as these talks from my good friend Heli. She is coming all the way from Helsinki, Finland to share her knowledge. Go to one of her talks and tell her The Data Warrior sent you!

I cannot believe how fast time flies! It has been an exceptionally busy year and that is the reason I have not had time to write blog posts either. I have been speaking in amazing events like BIWA Summit, APEX Connect, Riga DevDays 2017, OTNEMEA Tour in Baku and in Madrid, BGOUG, E4, KScope17, Oracle Code Bengaluru, the first ever APEX Day in Finland, Oracle Code Seoul, POUG, and Tajikistan TechDay. Next on my list is Oracle OpenWorld. As always it will be a busy week.

I will fly to San Francisco on Thursday to attend the ACE Director briefing on Friday at the Oracle HQ. I will have three talks:

And I will also have two short talks:

I will have several meetings, swimming, running and chocolate tasking

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/

3. Nov 27-29, Santa Clara, CA – http://www.scalefree.com/2017/03/29/data-vault-2-0-boot-camp-and-certification-santaclara-nov-2017/

#SQLDevModeler Tip: From Domain to Database… A Comment Conundrum

Great tip on creating a custom transformation script in SQL Developer Data Modeler (SDDM) from the awesome David Schleis:

Recently on the Data Modeler Forum, I came across this question:

Is it possible to mirror domain comments, from Domain Administration into attribute “Comments in RDBMS”?  Would like to mirror these to the ddl so they can be then available in column comments in the database.

I knew that one of the example transformation scripts provided with Data Modeler copies the column “Comments” property to “Comments in RDBMS”, so I thought I would point this out to the questioner, and that would be that.  But….

Drill to Detail Podcast: Data Modeling, Data Vault, and Snowflake!

My good friend Mark Rittman has embarked on a new adventure as an independent analyst and consultant. As part of his new venture Mark started a new podcast series on iTunes that he calls Drill to Detail where he will feature interviews discussing a range of topics related to data warehousing, business intelligence, analytics, and big data.

I was honored to be asked to take part in this new venture and got to spend a hour with Mark a few weeks back recording what is now Episode 5 of the series. In this interview we talk about:

The podcast is about 60 minutes with each topic being about 20 minutes (so feel free to skip ahead if you are short on time). Please have a listen and let us know what you think in the comments below.

Cheers!
