[Year 12 SofDev] DFD question

[Esther Andrews]

Think back to the DATA. If the assassinated receives no data (eg SMS message saying "You will DIE") then they don't go on the diagram. The diagram just shows DATA FLOW.

Subject: [Year 12 SofDev] DFD question

Hi all,

I am having trouble with aspects of a DFD.

I have a DFD and context diagram in which shows a customer orders a service and it is quoted and carried out.

Similar scenario, except the service is being carried out for a beneficiary. (Think Ninja and assassins. ;-) )

The Customer is providing all details and payments. The beneficiary is not actually adding to or receiving from the system (that I can see).

Are they still added as an external entity? Is there any connection between them and the system?

Many thanks for any input/
Simone
