This is the problem:

The Credit Union Analytics.xlsx File has FIVE tabs on it$.$

USE TABLEAU PREP to build a flow that:

Properly joins the data file tables together into one table. The tables join as follows $($Key fields for joins in parentheses$)$:

Member Demographics $($Member Group$)$ Joins to Member Group Info $($Member Group Code$)$

Member Demographics $($Identifier$)$ Joins to Loan App Info $($Identifier$)$

Loan App Info $($App Type$)$ Joins to App Type Info $($App Type Code$)$

Loan App Info $($Loan Purpose$)$ Joins to Loan Purpose Info $($Loan Purpose Code$)$

My question is would these all be joins in Tableau preps or would some of them be union tables as well? What sequence would I create the joins in$?$
