Context Diagram (1 Viewer)

[ezzy85]

I was reading some notes and they said context diagrams dont have data labels but we were taught they do. I called the advice line and they didnt know. They said "it wont hurt to put them on". SamD, or anyone, whats the story with the context diagram?

Thanks

A Context Diagram (which is the same as a 0-level DFD) has the whole system as one process, and has all the external entities shown. You also put the data that flows between these entities and the system. Dont put data stores.
