How do you want to use such database. My suggestion is to write
new driver for dbmi so that we would have one interface and
could switch to other RDBMS by selecting some other driver.

We use 'category number' for distinguishing more caterories on
one element and 'category' for what you call 'index' (id,key) in new vect
library (for grass51). Code is already written with these names.
('Category' is still only link to external database.)
