Memes come and go in this industry.
One popular one that's making the rounds is the Doeswijk Data Model, as described by my esteemed colleague and competitor Hu Yoshida over at HDS.
Now, I don't have problems with simple models to illustrate a concept or two, but every model (and analogy!) has its limitations.
In this case, I've now started to see a few people use this model as a basis for creating their overall storage strategy, and the results -- well -- haven't been pretty.
I do want to thank Hu for sharing the model. And while I want to praise its strengths, I also want to highlight a few key intellectual flaws that can lead you astray if you're not careful.
