In order to connect Tableau to Denodo Platform, I would follow the steps provided in the Knowledge Base article, [Connecting Tableau Desktop to Denodo](https://community.denodo.com/kb/view/document/Connecting%20Tableau%20Desktop%20to%20Denodo?category=Northbound+Connections). I would provide the following details to establish a connection,
* Server: name of the server where the Virtual DataPort server is running
* Port: ODBC port number, by default it is 9996
* Database: name of the Denodo virtual database you want to connect to.
* Authentication: select between the authentication methods provided:
* Username and Password: Uses standard authentication.
Hope this helps !!
