[Year 12 IT Apps] Quick Quiz - Decision trees

[Timmer-Arends]

Hello Mark

all of the below plus DeMarco considered decision trees/tables to be one way 
of specifying the actual process of a dfd 'process bubble' (ie, once you've 
unpacked all of the system to the lowest level of the dfd, you then have to 
specify what processing actually takes place, or is to take place, to 
transform the input to output - he called them minispecs). Therefore logical 
design tool is probably the best classification.

Mark
To me logical is what helps to make the decision clearer. I.e. how is
information flowing not what the information is flowing through.

A physical tool is about what is required. What devices.

I.e. the decisions about the house I want to build VS the physical plans
and wiring?

So I would go with logical design.
(but happy to be proven wrong)

Would you clever people categorise a decision tree as a logical or
physical design tool?

It seems to me to be the former since it's formulating the desired
behaviour of equipment but is not trying to set out how the behaviour
will be carried out or how the system will be built.

Cheers
