I'm trying to figure out id this is possible.
I have three cloned environments. Database A, Database B, and Database C.
Each contains their own customer data. What I want to do is combine the 3 so that when I select Customer I see the customers from all three environments.
Something like this...
how do I go about starting the joins if this is even possible.
I think you can use Tableau Prep and Union Your Data, because you may not be able to do this in Tableau.
