The Data Warrior

Changing the world, one data model at a time. How can I help you?

Happy 2013! What will you do this year?

Happy New Year! Welcome to year #2 of the Oracle Data Warrior.

I hope everyone is looking forward to a bright, happy, and successful year (however you measure it).

For me it will be a year of figuring out my long term business model (maybe?), writing a few more short ebooks (stay tuned), doing my Oracle ACE Director thing, continuing to work as a Data Vault and Data Warehouse advisor and consultant,  presenting at RMOUG, KScope13, and hopefully a few other choice events, and of course writing on this blog (and practicing my martial arts).

That ought to do it, don’t you think?

But you never know what life may throw your way, so I am not tied to any of that really, but that is where my wave seems to be heading today.

One thing I have already done was to take advantage of Vizify to build a visual story about myself. I really like the look and feel of the app and the way it presents my information. Check out the animation on the location page and then the timeline on the career page (which is not quite complete yet). Very cool.

How about you? What is on your horizon for 2013?

Cowabunga!

P.S. See this cool 2012 report WordPress generated automatically. It covers the stats I put in my last post but much nicer presentation. 😉

The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog.

Here’s an excerpt:

4,329 films were submitted to the 2012 Cannes Film Festival. This blog had 23,000 views in 2012. If each view were a film, this blog would power 5 Film Festivals

Hurry – Only 24 Hours Left to Get a Free Conference Registration

As I have written before, I love Oracle User Groups.

My two most favorite groups are the Oracle Development Tools User Group (ODTUG) and the Rocky Mountain Oracle Users Group (RMOUG).

These two groups put on what are arguably the best annual conferences for users of Oracle technology – by users, for users.

Over the past 20+ years I have attended most of their events – and NEVER paid a registration fee.

This was very helpful when my boss said there was no money for training. I just said “I get in free”.

So would you like to attend one of these events for FREE?

All you have to do is submit an abstract to present a session. If you get selected, your registration fee is waived. This is worth over $1000.

But you have to hurry, the deadline for submission is Monday October 15th, 2012.

Details:

RMOUG Training Days is  February 11-13, 2013 in Denver, Colorado. (Right in the middle of ski season!)

Go here to submit an abstract.

ODTUG’s KScope event will be June 23-27th in wonderful New Orleans.

Go here to submit an abstract.

I have submitted multiple abstracts to both events.

So what are you waiting for – go submit now!

See you in Denver and New Orleans in 2013.

P.S. My Kindle ebook  started out as a user group presentation. No telling what you might do with your presentation.

ODTUG KScope12: Day 1 Symposium Sunday

Wow. What a day!

Started off with leading a Chi Gung class at 7 AM to about 18 attendees. Great start to the day.

Then it was off to the races with the kick off of the BI Symposium, chaired by Kevin McGinley. I got to be “interviewed” about my  Data Vault Modeling session on Monday ( I will report on that tomorrow) , along with several other presenters. That was followed by a lively talk show-style discussion led by Kevin and Stewart
Bryson. Below see the room and audience in attendance at 9:00 AM on a Sunday. (pretty good turn out – way better than last year!)

The panel discussion was followed by a series of talks from Oracle BI product management. There was lots of talk about mobile BI, Oracle’s acquisition of Endeca and of course BI in the Cloud.

(At this point I switched tracks to the Db development symposium chaired by Chet Justice aka @Oraclenerd)

The next talk I attended was by Kris Rice (@krisrice) who gave an intro to Oracle SQL Developer Data Modeler. (Nicely he plugged my Data Modeler talk on Thursday)

Some review (for me) and some new stuff too. I learned his trick for showing the joins between views – use the view to table utility to convert the views to tables, add PKs, then use the Discover Foreign Keys feature. This creates FKs based on column names and know PKs.

Cool trick. Just gotta remember to set “generate DDL” to “No”.

Quick switch back to the BI Symposium to see some screen shots of a new look and feel for OBIEE with modern mobile themes.

More coolness…especially if you are an iPad sort of geek.

Back to DB dev land (is it lunch yet?) to hear Oracle product manager Jeff Smith (@thatjeffsmith) take about full lifecycle development using SQL Developer.

Lots of great tips from Jeff about generating table api’s, using version control, doing schema diffs, and unit testing.

SQL Developer definitely has lots of features I did not know about. Being able to define unit tests inside the tool seems like a valuable option. I will be getting folks at my client site to try it out next week!

Oh yeah – he also mentioned DB Doc for creating HTML documentation  on your code because code is never really self-documenting. Gotta check into that more too…

<Lunch break – yummy Italian selection of salads and food>

Post-lunch back to BI and Mike Donohue from Oracle talking about reporting on data from “beyond the data warehouse.”

Heaven forbid! (well I guess we gotta deal with it now)

So, Mike talked a bit about how Endeca Information Discovery can be used to gain understanding and build analytics on big and unstructured data. Mentioned “faceted data model” and generating a key value store. Sounds cool. Have to look into that too.

Mike also discussed using BI Publisher to allow users access to local data (in Excel, XML, OLAP, etc)  so they can build their own reports. Scary thought but, in some businesses it will make sense because in reality not all data is in an ERP system or a well built RDBMS.

Whata gonna do?

<Back to DB Dev>

No to hear the world-famous Tom Kyte (of Ask Tom fame) talk about his approach to tuning. It was, as expected, a full house.

Tom’s main point was not to necessarily tune the specific problem query but more holistically to look at the overall algorithm (or approach) that was taken to solve the problem in the first place.

In his experience many queries can’t be tuned all that much when what was written was not even the best way to solve the problem. He gave quite a few eye-opening examples where there was simply a much better way to accomplish a task than the SQL that was originally written. Seems many situations really require re-engineering the solution.

A nice take away (that makes you go “duh”):

More code = More bugs

Less code = Less bugs

Moral of the story – find the simplest solution. If the code is really complex, you are probably wrong (or at least over complicating it). Try again.

Last symposium session for the day (for me) was Maria Colgan (Oracle) talking about tips to get the most out of the Oracle Cost Based Optimizer.

Maria is the queen of the optimizer. She explained what the optimizer will do in several situations and why and if it is wrong, what you need to change to get it right.

Okay – already on brain overload (and it is just day 1!).

Need sleep.

Have my own presentation tomorrow.

And Chi Gung at 7AM.

C ‘ya

P.S. There were lots of tweets all day with more pictures of the event. To see them look for #kscope and @ODTUG on Twitter (or follow me @kentgraziano).
