I suggest that you look at Jeff Heflin's doctoral thesis (Towards the 
Semantic Web: Knowledge Representation in a Dynamic, Distributed 
Environment [1]) which backed the SHOE language with two different 
DBs - one was XSB, the other was Parka-DB [2].  Parka-DB is the 
current winner in putting an ontology into a relational DB (with 
respect to scaling and having some built in inferencing), and we are 
working on solving some licensing problems so that we can release it 
in some open source forum.
