Existence testing is absolutely to indicate that the user input is <i>not</i>
equal to null<br>
<br>
Existence in the 'Medicare database' is actually range testing pure and
simple irrespective of the study design.<br>
<br>
Don't think you'll get too much dissent on this one Mark.<br>

Have a great Xmas to you and all<br>

Validation types in the study design are:<br>

The<a href="goog_2101737954"> </a><a href="http://vceit.com/postmortems/2010sd/SD2010exam.htm#c4" target="_blank">2010 SD exam</a>
decided to muddy the waters by describing these validation tests:<br>
<br clear="all">
<i>Existence - to make sure that the number entered exists on
Medicare's database<br>
Null - to make sure something has been entered<br>
</i><br>
Now, I've always read "existence" as "has a value been entered?" (like
"Null" in the exam question).<br>
<br>
How many of you good folk refer to existence testing as "existence in a
limited list", and how many would equate existence testing as null
testing?<br>
<br>
If you agree that the exam's terminology is unconventional, I am a bit
concerned about it being used in an exam where it could confuse
students who were taught the conventional interpretation.<br>
<br>
Now I'm even doubtful about what the study design means by "existence
checking" - does it mean "null checking"?<br>
<br>
Have a happy winding-down time, if you're luck enough to have one!<br>
