[Zope] ZODB or MySQL for form data?

[paulporter at buffalotalks.com]

I'm coming to Zope from PHP where my database is MySQL. However I am
wanting to move to Zope and am trying to learn the correct way of working
in this platform.  I know that I can connect to MySQL from Zope but from
what I read it appears that the use of this feature is recommended only if
one is wanting to use an existing database. Since I am starting a new Zope
application, and will be creating new data files, is it better to use
MySQL or ZODB to handle form data?

I would really appreciate hearing from experienced Zope users on this matter.
