I take Amazon as an example. They have many different goods to sell,
which have different properties, e.g. books, DVDs, electronic stuff. 

A book has an author, which is relevant for Amazon[1], a digital
camera has not.

While sometimes these different properties are relevant (data mining,
shop browsing[2]), when on an invoice, they are all the same. It would
be inconvenient to provide for seperate relations from the invoice
object to book objects, to DVD objects, to electronic article objects,

[1]  They use this for data mining, inter alia.

[2]  They have different categories for different article types.
