And dataflow & databases. One of the people working on it once
explained it to me as (at least partly) an attempt to create
a functional, dataflow version of relational algebra. That is
[if I'm remembering correctly], you could take a "Select" object
and plumb it into a database relation object and then plumb the
output of that into another database relation object and get a
wire coming out that had the query results of the "join" of the
relations (or something along those lines). The idea was to use
high-enough level models for the dataflow that you could get
significant parallelism going, just as another poster was asking for.
[I don't know if they ever got that far...]
