[Year 12 IT Apps] Quick Quiz - Decision trees

[Mark Kelly]

Thanks, Andrew and Robert.  I Googled for "Logical design tools" and it 
came up with zilch.  It seems to be a concept unique to VCE IT  :-)

On a similar note, the accepted industry SDLC seems to be rather at odds 
with the one in our study design - for example, "feasibility study" 
usually appears as a separate initial step, and "maintenance" is usually 
  the last step.

I occasionally get this nagging feeling that we're playing in a theory 
world that doesn't quite match the reality of industry.

A conclusion is the place where you got sick of thinking.
If you Declare War - is it integer or boolean?
