A Data Architect’s Initial View of Data Vault

Wow this is really cool! A long time, experienced, Kimball-style architect had this to say (and more!) about the Data Vault:

The more I thought about it, the more I began thinking a traditional staging area and its complexities are a huge headache!  The simpler design using the data vault methodology as the persistent staging area offers huge benefits over the traditional Kimball style data warehouse staging area.  This includes repeatable code use in building and populating the data vault as well as the ability to easily account and validate the data.

(see more at A Data Architect’s Initial View of Data Vault | Making Data Meaningful.)

That pretty much says it all.

Ready to learn Data Vault now?

Well then get to it! Go to the learning portal and sign up or at least go buy the book!

Alert would-be Oracle Warriors: Chi Gung in San Antonio

As many of you now by now I will be presenting several sessions at the ODTUG annual conference, KScope, this coming June in San Antonio, Texas.

What you may not know is that I will also be conducting 30-minute Chi Gung sessions in the morning before the events of the day start as part of the KScope12 Fun Factor activities.

Why you may ask?

In short, because even geeks need to exercise to live long (and prosper).

Plus this type of moving meditation is just what the doctor ordered to help you de-stress and (mentally) get away from your daily IT routine. (I have written a bit more on this here and here)

So as some motivation for you to join me doing Chi Gung (in the cool part of the day!) check out this video of a guy Exercising Around the World.

If you like that video and a really motivated, check out his web site at NerdFitness.

At KScope11 in Long Beach, we did it everyday and had at least 20 people each morning. It was a lot of fun.

Here are a few of the comments I received about the sessions:

“Kent organized the Chi Gung class at this years ODTUG KScope 2011 event, which was very enjoyable. A very relaxing way to start the day. Kent explained the exercises very clear, which made it easier to follow for first time practitioners.” 

“Kent proivided Chi Gung sessions to supplement an IT conference. It was a great way to set us up for the day and it was great fun. Ken was patient and yet educational, repeating the main concepts each day for new people. I attended for 5 consecutive days and would have loved to have done more” 

No previous martial arts or meditation experience required!

Let’s join the revolution and become fit and healthy Oracle Nerds and Geeks!

Tell me in the comments how you are becoming a fitter, healthier Oracle geek.

Then meet me in San Antonio for some moving meditation, relaxation, and fun.

How’s your surfing?

I read this today on one of my favorite blogs – Zenhabits, and it definitely spoke to me:

We are not walking a path, but surfing a sea.

Most people look at goal setting as picking a destination, then figuring out a path to get there. That assumes you’re walking on land that will change very little, and that while you will have unforeseen obstacles, you’ll be on stable ground and the destination won’t move. That’s not at all true — life is more like the sea, ever changing with no fixed paths or destinations, with swells and currents and waves that change everything at every moment. The ultimate skill, then, isn’t setting a destination (goal) or a path (plan), but surfing. In surfing, you take whatever waves come, learn to judge the waves as they come, learn to ride the wave as it changes, not as you planned. It’s going with the flow (literally), and changing what you do depending on how the flow changes. (via » Why We Overplan :zenhabits.)

For years, every time someone asked about how I got to where I am in my career, I often found myself at a loss to give them a seemingly satisfactory answer.

What Leo wrote above articulates really well what I have been doing (unconsciously) most of my life – going with the flow. I have only been on surfboard once (yes, even data warriors surf) but the analogy fits really well in my mind. (BTW – A good downhill ski run or shooting some white water fits too)

It “feels” like the right answer.

Oddly (or not?) it fits with a classic quote from my martial arts hero Bruce Lee: “Be water”

Pretty Zen, right?

So what does this have to do with data modeling, data warehousing, etc?

Mostly I have found in doing agile (or agile-like) projects, the team needs to be like water, or really like a surfer on the water, and go with the flow through the sprints and iterations.

Changing directions at a moments notice as the users needs and priorities change.

Embrace the change.

Doing so without judgment or expectation.

Flow around the obstacles and blockages – or risk crashing on the reef!

So, let go of all the goals and set-in-stone project plans. Embrace the flow and see where you might go.

Who knows, you might hang 10 on the biggest wave of your life!

Aloha.

P.S. If you want to learn to be a better data surfer check out the Data Vault Learning Portal and learn how to implement the most agile data modeling technique around – Data Vault.

What’s in your war chest?

When you gear up to do battle with your next data warehouse or data modeling problem, what are your weapons of choice?

ERwin?

Oracle Designer?

SQL Developer?

Or do you go “old school” with the traditional pen and paper (or marker and white board)?

Whatever your approach, everyone has a favorite. Tell me what yours are in the comments.

Take care out there.
