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...
