I'm not sold about both the OQL interface and the Introspection
interface.

Instead of the OQL interface, we could use the query tree system from
common that forms uses internally now. This could be the better way than
to let Forms translate the query from tree to OQL and let the Appserver
translate OQL back to query tree :)

On the Introspecion topic, I play with the idea of allowing
introspection by pseudo business objects (like you query an object class
"sys::classes" and "sys::fields" etc.). Like most databases do it on
table/column level anyway.
