[Zope] database design question

One thing I highly recommend is not using zclasses. Learn enough of python
products to do a restaurant as a python product. Long term they are more
maintainable and more reliable from my experience. I have not been happy
with zclasses for many reasons. With the kind of load you will have a
python product will probably be best.

could you elaborate more on that by giving the reasons why not to use
zclasses in some/all situations ?

thanx,
