[Year 12 IT Apps] IT applications 2007 exam: assessor's report

[Mark Kelly]

I see Section A Q9 had no comment by the examiners...

"Validation is used to
A. check the accuracy of calculations.
B. detect software errors and alert the manager.
C. test functions and alert programmers to errors.
D. prevent inaccurate data from entering the system.

The official 'right' answer was still steadfastly 'D', which is rubbish.

It cannot be D because validation does NOT check the ACCURACY of data, 
only its reasonableness.

Even the sacred IT glossary says validation checks data input to a 
system is of an "appropriate type for processing, and within acceptable 
boundaries")

So are we to accept that validation is used to check the accuracy of 
calculations? No - that's called testing.

Hmphh.
Not happy, Jan.

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