To jump in here, the DataStore API was developed specifically to provide
live connections to DBs. The DataSource API was old code that was just
our first quick attempt at abstracting the concept of connecting to data
sources. It was basically obsoleted by the DataStore work.

Hi Paolo,
Thanks for your thoughts. I'll defer to your experience in implementing
database plugins since I wasn't directly involved with coding the ArcSDE
plugin. The problem I have with the DataStore ArcSDE driver is that it is
inherently multithreaded when you have more than one layer, so it

Stefan,
I haven't been able to test Larry's mod to the BasicFeature class or
his plug-in that uses this method. I'm afraid I've been putting in
some long hours at work, and haven't had time for any coding. :[

I was going to ask by the end of the week if Landon tested it and if we
can add the method. Basically I just trust you on that (having way more
developer experience than I have).
sorry that databases are not my area if expertise - although I may know
some very few things about it
