with respect to MAPSETs and LOCATIONs, the "DATABASE" is nothing to do
with DBMS to hold vector attributes, it is the master directory which
holds all your grass data. It's the "$GISDBASE" in the above path to the
dbf directory.

this "database" verbiage long predates any DBMS functionality in grass.
in grass the use of that term probably predates the IBM XT for that matter.
