Hi Neo,

How many humans are built around a predefined data model?

Ah, the grand EAV design. Yes, I've seen it.

I've also once seen a set of procedures that allowed me to play checkers on SQL Server. Apparently, someone had way too much time on his hands, so he decided to prove that it's possible. Does this mean that SQL Server is now the ideal game platform? Of course not!

The mere fact that something is possible doesn't mean that it's a good idea. That goes for playing checkers on a database, and it also goes for the EAV design. Systems built around the EAV design have a tendency to break down - usually in one to two years.
