Oh ho ho ho. What weird things we use as a databases. I remember when I first started out as a consultant developer we were using a CMS as our data repository because someone thought that was a good idea. (It wasn't). The vendor was flown in from the states to help troubleshooting. I will never forget how he looked at me when I had to explain to him why we made so many nodes in the content tree, it was because we were using the CMS as a repository.
