@Hi all ,
I am new to tableau i have below questions,can anybody answer them ?
1 .Before start creating dash boards or any reports in tableau , do we need to create logical data model in tableau like we create in microstartegy ?
2.In training videos all the practices were created based on EXCEL , if i want to work with DB's like teradata,,etc then is it the same process like excel ?
Yes, Have to create data model.
Once you connect to the database then drag the required tables on to the view trhen define the JOINS as per busniess needs.
