[Year 12 SofDev] Internet in a DFD

[Adrian Janson]

Hi Mark,

I would think it is effectively an external entity - however, if an order
was received from the Internet, you would probably re-label it 'Customer'.
'Internet' is really too vague a term to put into a DFD.

My thoughts...

Cheers,
Adrian

Hi all.  When putting the internet into a DFD, does it count as an 
external entity?  Or doesn't it matter, logically speaking?

Is it treated as just another data store or data source/destination: 
e.g. an order arrives from external entity (the customer) without caring 
how it arrived?

I may have answered my own question...
