I'd like to say I don't like these questions - but looking at the posts I appear to be in the minority!

Anybody else out there with me?

But I wonder how long it will be before someone claims it's a trick question?

Trick question!




Just kidding, of course. Thanks for the question. I think I encountered the term Heath Normal Form once, but too long ago to be able to answer the question without the help of my good friend Google.

Google too (it's been a while since college, and theat's the only time I've really known all the names of things). Of course by now, the top hit on Google for "Heath Normal Form" is this question itself!

I have to say I'm with you on this one, Paul.

I do acknowledge that different people have different styles of learning and working, and for some people memorizing all the nuances of normalization theory may genuinely help them in their work.

However, the fact that Hugo admits to having to Google this one might suggest that this question is a little on the esoteric side, and that you could be quite good at your job without knowing or caring about the answer!

I don't for a moment imagine that knowing that Chris Date suggested that Heath Normal Form night be a more suitable name than Boyce-Codd Normal Form would help anyone in their work (unless perhaps their work was writing a book about the history of relation theory development in the early years). But a lot of people find this kind of trivia fun, and there's always the hope that some people will read up either the papers referenced in the explanation or some of the things they find when googling for an answer and learn something useful from that.

Those are valid points, Tom.

I'm quite happy to see questions like this appear from time to time; they just don't suit me personally.

And maybe I'm just a little bit grumpy today because I lost my 2 points!

I think that if "you could be quite good at your job without knowing or caring about the answer" is the measure for the QotD, then we could remove, depending on the exact job people are doing, somewhere between 80-90% of all questions.
I never use BI in my work. Yet, I like QotD questions about BI, because they force me to look into technology I normally don't use, and help me learn. I also like trivia questions like this one, because I like to know a bit more than just the bare technical knowledge my job requires - and I also hope that this question will contribute a bit to making the issue and importance of normalization more well-known.

I could surprise you here. After setting up my scripts to capture wait state differentials from my production server. I had to bumble my way through PowerPivot to develop some nice quick and easy to use dashboards on the BI server so I could analyze them easily and simply.

If I didn't feel like a bumbling PowerPivot fool, I think I'd write a PowerPivot article for SSC. Some of the rest of the BI stuff from MS can be wonky (Report Models/Report Builder amaze me at how stupid some of the parts of them work compared to something like Crystal Reports, and SSAS makes me scream when I want to do something that seems to be relatively simple and leaves me befuddled), but PowerPivot is a nice simple and powerful tool (I guess until I want to calculate a median, since it's an SSAS derivative that will likely cause me to start the screaming fest all over again).
