Tableau licenses are purchased centrally by Information Technology Services through a chargeback to your department. In addition to the license fee, there is a yearly maintenance fee which entitles you to software updates. For license availability and pricing, contact Cherie Judd, ITS at cjudd@uwf.edu or Ext. 2559.
You can download a 14-day trial copy of Tableau Desktop for free. Once you purchase a license code from ITS, you can register and keep the trial copy.
