[Zope] MySQL and/or ZODB

[Mitch Pirtle]

There was a discussion on the Zope-DB list about this, and I vaguely
remember that ZODB was really good for objects, and that's it.  The
debate really turned into a MySQL-vs-PostgreSQL debate, which although
slightly off-topic, proved that we all agreed that ZODB was not suited
for heavy data use (although we couldn't agree on the DBMS) -;^>=
