Obviously, you're going to need data for the products in order to view and/or edit them.  Maybe you're asking if you can avoid have to manually enter all the data into your database.  Maybe there is something or some service like that in your profession.  In my profession (retail), I sent my company's product info (style, color, size, UPC, etc.) directly to our clients' system so they didn't have to manually enter anything.  I don't know anything about your profession so you need find that out for yourself.
