Excellent! I can see that I'm missing some notation conventions I'll have to dig up to get all the way through it (for example, L[N] in the definition of a list-valued attribute doesn't provide me with enough information until the next def which tells me the domain, so I gather that L[N] is the label for any vector consisting of elements in the domain of N)

I love the domain of lamda as {ok} -- I don't know if there is a history for that or if these guys made that up (to indicate null as a value, if I'm reading it right).

 I sure would have preferred a nice little business data processing example over the nucleotide sequences but the multivalue dependency work looks right up my alley, if only I understood it. smiles. --dawn Received on Sat Jul 03 2004 - 17:24:15 CEST
