That was what I was trying (unsuccessfuly) earlier to state - that if
you need a RDBMS, then use one; and if you are storing objects, then
ZODB is the way to go.

For me it always was clear, but to some there is no difference between a
RDBMS and an object store.  My earlier reference to ACID was to point
out that your requirements/functionalities are different between the
two, and there's a good/bad time to use either.

For example, if you needed to support transactions over multiple pieces
of data, why would you dump it in an object store?  And if you needed OO
functionality without any clear needs for referential integrity (and all
that other database stuff), then why put it in a RDBMS?

I think the name is great.  Here in Switzerland, many people try to
pronounce acronyms (like "U.F.O." as "ufo") and watching them try to say
"zodb" is really worth taking the time...
