Creating an ecommerce store WITHOUT a database seems archaic to me (and a waste of time). A spider only sees the HTML code that is generated by the server. Any savy programmer can use a combination of scripting, mod_rewrite, and database calls to create a fully-spiderable website that is generated from a database. If your guy is good, the bots will never know that it isn't a static page. Sticky me if you need more information.
