[Year 12 SofDev] sofdev Digest, Vol 96, Issue 6

[Russell Quinn]

The normal guideline is no more than 8 processes
on a level 1 DFD. All top level labels like Manage
Applications which could be broken down in lower levels
to accept appln, validate appln, verify appln data etc.

Regards,

Russell Quinn

My class this year is having more trouble understanding DFD's then past years

In particular they seem to be reading too much into processes -they are often breaking down the data flow into far too many processes then I was expecting!!!

I do understand this is the case of a DFD  once you go through the levels (e.g. 2, 3, 4, etc.) but they are doing this on a Level 1 DFD

Is there a definition of a process (at level 1) that might be able to help me (and them)?
