Basic Connections of Data Source

To test your Tableau data, you need to connect Tableau with one or more than one data source. Further, a Tableau data source is as much easy as the Excel Workbook. Once the connection is established, the data fields will appear in the Data Window. You can connect to any supported data sources that this tool supports such as multi-dimensional databases, SQL databases, etc. 

Moreover, there are certain steps to follow to connect a Tableau data source.

Moreover, you can connect Tableau data in another way where you have to import it from a workbook. A workbook may contain multiple worksheets which you can attach to different data sources. For this, you need to click on the “Import from Workbook” button under the Select Saved Connection option. It exists within the menu- Connect to Data- dialog box. You can see the Tableau Data Source fields shown on the left side of the workbook under the Data Window section, upon the connection is set up.

Export DB connection to Tableau

Once we linked to the Tableau data source now we have to export the data connection in another way. This system allows connecting faster without opening the connection dialog box again.

If you regularly link to a similar data source many times or if you have coupled custom fields to the Data window such as calculated fields, and binned fields, etc. Therefore, for those links to that source, use the shortcut way or another way. This will help you to avoid the re-establishment of the custom fields.
