Normalization Myths: 2 New Blog Posts

imageI have a series of blog posts going up on  The introduction went up a few weeks ago and now 2 new rants have been added. Head over there to check them out and leave comments. I love when people leave comments — even if the comments disagree.   One of the things I’ve learned over the years is that performance tuning is something we learn by sharing experiences with others.  It’s not something that one can apply a bunch of formulas and rules to.  So post away.

Normalization Myths that Really Make Me Crazy – Introduction to a Rant

Myth 1 – Normalization: Friend, Foe, or Frenemy The Survey 

Myth 1 – Normalization: Friend or Foe The Slogan




Perhaps what the data profession needs is a series of top-up courses, to be reviewed every couple of years.  Maybe what we need is an intervention to help people understand the why normalization is even a topic in design.  I think this would make for a wonderful lunchtime presentation.  Perhaps your boss could even buy lunch.  This presentation wouldn’t be the how of normalization, but the whys and why nots.  Mastering the normal forms is fairly easy.  Understanding which one to use for a specific solution is the hard part.  The more your teammates understand the whys, the more likely they are to going to support your efforts.

Dataversity: Zombies, Zachman, Mason-Dixon Line and Normalization Rants

Two of my posts are now up over on, a portal of all things data for data professionals.

The first, now with images working correctly, is Hiring Data Professionals: Mason Dixon Lines and Zombies in Your Job Postings. In that post I reflect on some of the craziness in job postings I’ve seen over the last few months.


In my most recent post, Normalization Myths that Really Make Me Crazy – Introduction to a Rant, I start a series on normalization myths. I expect this series to provide hours of new content for my Contentious Issues presentation.  In the introduction I talk about why a series and the emotions people feel about normalization.  Please stop by and leave your thoughts there.


I’ll be writing more than a dozen posts for Dataversity this year and I appreciate your reading my posts there as well as those here at InfoAdvisors.
