It doesn't sound like you want a CMS. It sounds like you want something that specifically publishes a product catalog, more like an e-commerce app. Most CMSes are designed more around articles, with a looser data model.

If you do want to try to get a CMS to handle your content, it will need to be one that you can customize the data model of. I currently use and contribute to Krang, and I believe it is the most customizable system I've seen in Perl, but it still may not be enough to adapt to your data model.
