In my view, "A', "C" and "d". Any thoughts??
I understand where you are coming from Deepak Rai. You can have all three in your extract.
These are not connection type(s) though. Correct? Donno, why this question came in the Certification ..
But, when it comes to the extracts, we do have Full and Incremental concepts/feature where in the Backend they will use some joins to get it worked (This is my understanding).
Also, I assume in the answers they will allow any one of them.
In this case i may opt Joins (Option A).
If they allow multiple options, then
i am confused and join with harris.tsr to select which one i should choose and finally opt for "A" which whether it is correct or not .
Will wait for other experts and see what they suggest.
You could select multiple answers in this one. I chose all four because A, C, D are essentially a type of join and not sure why I put B as well. I thought that if you only have a blen of two data sources you still can create an extract...
I've requested the full report of the answers, I'm really curious to see what I did wrong and what I didn't.
Oh ok I see. I'm not good at theory and I probably missed that. So, when you blend two sources on a field, aren't you able to create an extract? I was under the impression that I can blend the sources and the do the extract. Good to know, thanks
Looks like I was Correct
No, you can't blend and then extract. Blending is strictly when you have multiple data sources in Tableau (after you've connected to them) and then you want to connect. To blend (using the strict Tableau definition) you must have 2 datasources, so you can't create an extract from that. I'd have to check the cross-database join (is that what you mean by a cross-join ?) Join & Union are definite extract candidates.
Data connection type(s) is required to create an extract?"
2.cross joined table.
All three like A C D can able to do extract ,but in the case of blending it will create the extract separate for each data set, instead of combined .
do you face any problem with .twbx file in the exam?
please can you reply or anybody please reply me
