[Year 12 SofDev] Resource flows in a DFD

[Adrian Janson]

Hi Mark,

Hmmm... interesting.  I must confess that this is the first time that I have
seen one.  In ways it makes a DFD a bit 'muddy' though - making it a mix of
physical and logical elements.  Not sure if I like it.  I am not sure if it
is industry standard - some others may know?

Cheers,
Adrian

I can't remember seeing a resource flow in an SD DFD, but apparently 
they exist (e.g. http://www.getahead-direct.com/gwba03-context-diagram.htm)

Are they deliberately avoided in SD or are they not industry-standard?

Cheers
Mark
