Thomas, I think your best bet would be to read the introduction in this 
doc: http://www.rushflat.co.nz/files/GSOpenQM-1.zip

Brian does a much better job than I could is explaining Multi-Value 
databases.  Understand that the guide he wrote hardly refers at all to the 
GPL version of OpenQM (which is a shame, but there you go), but everything 
in it applies to the GPL version of OpenQM.

I use a Multi-Value system called Pick D3 at work and I've been a huge fan 
of MV since '86 when I was first introduced to it.

SQL databases are more organizationally complex (to me) than MVDBs are. 
For example, a product that was looked at to replace my ERP system 
required over 20 tables to describe an order.  My system does it in 2 
"files".   (one for order headers, one for order lines)
