Chris,
We have built a tool called Paasporter that extracts Quick Base data and will build a SQL compliant DB. Connection to BI is the first reason we did it. I have a couple clients on Tableau and their developers needed to be able to use the standard data source connection and write SQL queries against the QB Data and other sources.
I would be happy to show it to you. Once you have SQL the other side can be virtually any standard development tool.
