Hi Kim Vinson,
I dont know about the Retail Pro 9 . But you are talking about creating some views or dashboards which will get the valued information.
You can have a look at this video . how tableau can be used in Retail Analytics:Leveraging Tableau for Retail Analytics - YouTube
I have integrated Retail Pro version 9 and Retail Pro version 8 with different BI and reporting solutions fell free to mail me if you need any support related to Retail Pro.

Were you able to find some more insights on how Tableau can make connections to Retail Pro 8 or Retail Pro 9? Currently Retail Pro is asking us to use one of their Info stations to connect, I don't know if that provides a restricted entry into the database layer.
