This is a bit OT now, but yes, you're right. I'm remembering a situation
around 2 years ago, I friend of mine was running an internetshop
(running with a commercial software) for a pretty big german
hardware-seller, the backend was mysql. When the site was more popular,
the machine started to slow down heavily.

We've analyzed the logfiles with a small perl-script I had wrote, and
changed the database a bit, added indexes, etc. The result was a shop
that was around 3 times faster than before.

So, never trust in a DB-Design that's shipped by some vendor, look at it
yourself :)

To go ontopic again, using a SQL database as a pure storage (Everything
with a single index is pure storage for me) is like shooting moles with
nukes ;)
