By the way the "interface" approach mentioned in this thread
occurred some 30 years ago as part of the Structured Design
methodology introduced by Larry Constantine. The first
stage, Structured Analysis, was based on the use of
"dataflows", consisting of only 5 symbols: inputs, outputs,
processes, data stores (persistent data), and connecting lines.
The inputs and outputs represented interfaces to the
"external" environment while the connecting lines contained
the "internal" interfaces. Once complete a relatively simple
algorithm existed for transforming the network of dataflows
into hierarchical set of structure charts. I suggest you
reference some of the books by DiMarco.
