Preparing a Data Source
Before you start with MetaMiner, make sure your Tableau data sources are configured, or create the new ones.
MetaMiner Tableau Edition is able to connect to multiple data sources, simultaneously.
Connecting Tableau to PostgreSQL¶
-
Open Tableau Desktop (or Tableau Web UI). Install Tableau Desktop if it is missing.
The Tableau welcome page opens.
-
In Tableau Desktop, choose File – New and click Connect to Data:
The Connect widget opens.
-
Choose PostgreSQL in the Connect widget:
If PostgreSQL is not in the Saved Data Sources list (this happens the first time you connect), click More... and choose PostgreSQL from the full list of data source types:
Finally, the PostgreSQL connection form opens:
-
Specify your database settings:
- Server: hostname or IP address of the PostgreSQL server host
- Port: TCP/IP port
- Database: DB name
- Username: login
- Password: password

-
Click Sign In. If credentials you provided are valid and the database server is available, a new data source will be created and displayed:
Otherwise, an error message will be displayed.
