[Year 12 IT Apps] Qu A 15

[Robert Hind]

Now we have to add "claculations" to "refleact" as items that passed through a data validation system. So validation does not ensure that inaccurate data gets into a system, it only tries to do so.

It prevents them being used as a number in claculations etc.

When there are soft brackets and spaces, it must be text since text is
alphanumeric. 

Why no numbers for postcodes? 4 chars, limited range, all number.

I have a beef about this topic.
Some years ago I attended an advanced Access three day course to get my
head around this database program.
We were told in no uncertain way, that one should NOT use number as a
data type for phone numbers or postcodes etc. In fact it should only be
used when you intend doing mathematical calculations with it's contained
data further down the track.
Therefore, I choose A for Qu 15 (Part A), but in doing so remember one
or more of the VITTA practice ITA exams that indicated it should be
number.
What do others think?
