Question: We just upgraded to 2020.2 and when I view the data source screen, I no longer see my joins that were in my data source before. Where’d they go? Do I have to rebuild?
With the release of 2020.2, Tableau has unveiled many new features, but the largest component of the new release is the data model changes. The new capabilities are referred to as relationships. With them, you can define matching fields for use in analyses you build where Tableau will bring the right aggregation from the right tables as needed. The need to pre-aggregate can disappear for some.

The diagram below shows how the layers are split where you can define joined and relational information to create new and in-depth data models for your reporting:
This answers the question at hand, so I’ll stop this post here. However, if you are interested in learning more about this new data model and its full functionality, view our Assist Feature Demo replay for more.
