In VITTA's 2012 exam 1, A2 I would accept either C or D as correct. <br><br>The solution says that data flows from external entities to a process is not allowed - which I agree with. <br><br>Option D - data flows from "data file to external entity" - is also not allowed (see Adrian's text, p.49) so I'd accept that answer from students too.<br>
<br>The only reason I can see to rule out D is the term "data file" instead of "data store", but surely that's not significant, is it?<br clear="all"><br>-- <br>Mark Kelly<br>Manager of ICT, Reporting, IT Learning Area<br>
