ZODBC is a level 2 (at most, if not a level-1 still) Database adapter...
http://www.zope.org/Members/petrilli/DARoadmap
...this supports a global lock on all transactions which will block incoming
requests.

ZmxODBC DA is a Level-3 (multithreaded support)

Which one is better depends upon your need for the adapter.  ZmxODBC costs
$30.00 while ZODB is free.  ZmxODBC solved the "hang-time" issues we had
with SQL Server queries on our website(s).

I am curious of how popular SQL Server is among Zope developers.  We have
recenly upgraded from SQL 7 to 2000 and noticed most of the database support
for Zope centers around Oracle, MySQL, Postgres, Sybase, etc...

How many people are using this ZmxODBC database adapter?  And what kind of
problems/issues/praise do you have?

Any info would be appreciated.
