What Is Default Data Blending Join? |
|
Answer» Data blending is the ability to bring data from multiple data sources into one Tableau view, without the NEED for any special coding. A default blend is EQUIVALENT to a left outer join. However, by switching which data source is primary, or by FILTERING nulls, it is possible to emulate left, RIGHT and inner joins.
