I think the discussion over the last couple weeks indicates that this
SIG has more work to do. The DB-API defines a minimal general purpose
API for accessing SQL, but we need to keep the SIG open as a place to discuss
implementation problems and to support the development of solutions to
specific problems, such as establishing a standard interface behavior
for transaction processing. Perhaps a transaction API should be the
next target. I think Eric Newton was doing some work on a transaction
interface a year or so ago and Jim Fulton work on Bobo probably means
he has will have something to say on the subject.

Yes, more databases would be nice. Another problem is a lack of a
test database with test script to demonstrate conformance and
performance of the DB-API. (It could also make a nice demonstration.)
Some code that may be useful in building a test suite might be found
in the SQL tests at http://www.nist.gov/itl/div897/ctg/sql_form.htm.
The Conformance Testing Group (http://www.itl.nist.gov/div897/ctg/ctg.htm)
developed this test suite. The group have redefined their mission
recently. I found this quote in one of there documents:
NIST is exploring broader based methods for accessing unstructured
information, including natural language queries, and new mechanisms for
object-oriented access to multimedia data.
I don't know of anyone in that group who is looking at Python. I
guess that means that industry hasn't ask them to research the
Hint, Hint, nudge, nudge, wink, wink, know what I mean?
