Thanks Stefan. Also, as far as the best database base class to consider, we
have DataSource which loads the layer into memory, and DataStore which
doesn't but is read-only, and IMHO has problems with multiple layers due to
threading. I guess, if I was starting the task of implementing a new
database driver, I would start with a DataSource driver. Then once I had
that working I would implement a DataStore driver. Then I would consider
how best to fix the DataStore model so that it is more reliable and supports
read/write. There is also the option of building a new database base class,
but it would require a lot of core mods to integrate into File->Open, etc.
