i'm not sure i'm reading right, but it sounds like you
could add an is_active boolean column.
if the boolean is true, the product is considered
active.
if false, the product is considered "deleted", even
though it isn't eally deleted.
deny permission to delete from the products table.
you will not accidently lose any products this way.
if you *absolutely* know you want to delete a product,
you can do so manually - or set up an interface that
allows for deleting and deny access to ordinary users.
i hope i understood correctly.
good luck.
