Hi List, I've struggled with this one for quite a while, at least partly due to my previous experience being with *SQL dbs. I'm building an e-commerce site on Zope, and I've gotten to the point where I could see some huge advantages from a management perspective to doing catalog products as a zope objects, rather than table rows in MySQL. But, probably due to lack of experience, there are things that don't quite click for me yet. One of the main things is being able to easily and arbitrarily manipulate large numbers of products. Performance is another thing I wonder about. Basically, I would love to get advice from someone who has built an e-commerce site entirely on Zope, and any particular caveats they encountered. I'm very frustrated at this point because from a perspective of sense, products work great as objects, but not so well as rows in table. Thanks for any help you can lend, Alec Munro
