1. Re: What is underlying database structure of the Tableau engine?

It's PostgreSQL. I just followed the directions in this link to assign a password to access the Tableau server database just the other day.
http://onlinehelp.tableausoftware.com/v8.0/server/en-us/adminview_postgres_access.htm
However I haven't had any time to play with the tables yet. I would also benefit greatly from learning more about the structure of these tables.

1 of 1 people found this helpfulUnless you work at Tableau you won't get most of those answered. You want to look at the Admin. manual here to access the views within the db that Tableau is allowing us to see. To really get into the guts of the db use DAAP but you're on your own at that point.

3. Re: What is underlying database structure of the Tableau engine?
John McGraw Jan 15, 2014 4:10 AM (in response to John McGraw)My thanks to both Michelle & Toby. There answers pointed me in good directions. However something else that I would appreciate is a field dictionary of some sort. For example, the _views_stats has a field named nviews. Does this represent the number of times a workbook has been viewed? I can likely figure most of them out eventually, but it would be much more efficient for me to have a dictionary of tables & fields with their descriptions/definitions. Does such a thing exist?

Michelle Eich Jan 15, 2014 5:56 AM (in response to John McGraw)Hi John,
In my search of the forums I’ve never found a dictionary….
Perhaps you already know this but it might help to decipher what fields each table has… Tableau Server does include already created views on the Admin - Maintenance side under the Analysis section such as Server Activity, User Activity, View Performance History, etc.

kettan Jan 15, 2014 6:05 AM (in response to John McGraw)You might like to vote up Easy access to metadata on Tableau Server and thus influence Tableau Corp. to make it easier to access user hits in a future version.
Until then you might find a way by studying following:

John McGraw Jan 15, 2014 6:16 AM (in response to kettan)Many thanks to you all. Ketan's link to "Better late than never . . . " is exactly what I was looking for. Only hitch is that the actual diagram did not download, but the other views contain descriptions for each table & associated fields. Thanks again to all!

Russell Christopher has also written about History Tables (new in version 8 I think) which probably should be included in your studies of Tableau Server metadata:
