In this section, we will teach you how to set a Tableau data source. A Tableau data source contains data connection information that describes the data you want to bring in Tableau.

The section will explore in details how to get your data ready for analysis through; building relationships, data joining, data blending, data union, pivoting data, working with Tableau interpreter feature and splitting a field into multiple fields.

Once you grasp how to connect and prepare your data, we'll teach you how to set data source filters to limit the amount of data in the data source or restrict the data users can see, before showing you how you can extract data (to improve performance ) in Tableau.
