Re: predicates as verbs

Henry


 I am not trying to convince you or anyone of anything, I am reminding you
the way it is

the practice of data modelling is established, and there are a few, key
fundamental rules
that make things work, afaik the predicate as relation is one of them
(unless you can refer me to different practices)

relations need to be verbs if you want the data model to be sound in an
economical way
and possibly within my lifetime


of course, everything else is possible too, you ll just have to find the
time to make it work

let me know when you do?
