I would also add in hindsight that the distinction between something
that identifies a proposition and something that identifies the
entities about which those propositions speak is an extremely
important distinction to make. I think this often gets confused,
generating confusion and miscommunication. Indeed I imagine this is
the very reason why Codd chose the term 'key' instead of 'identifier'
when it came to defining attributes which make a certain proposition
unique.
