问题
I have used two data sources in a tableau. First I loaded sample xlsx file provided by tableau Sample - Superstore.xlsx with table Orders. Then in the Sheet->Data->New Data Source I loaded one more xlsx file Sales Target (US).xlsx.Internally the relationship is mapped between these xlsx file tables If we see in Data->Edit blend Relationships.
I just wanted to find where these internal relationship details is stored in the xml structure retreived from .twb file obtained on unzipping the .twbx tableau application if we load the datasource as I mentioned above
