Question 8

What are three reasons to use joins instead of relationships? (Choose three.)

    Correct Answer: A, C, D

    The three reasons to use joins instead of relationships are: when you need to use a specific join type, when you need to use row-level security, and when you need to use a data model that supports shared dimensions. Using a specific join type allows for more control over how data from different tables is combined. Row-level security is often implemented via joins to restrict access to specific rows of data. Data models that support shared dimensions can be more effectively managed with joins.

Situations where you might still use joins include when you want to: • Continue to use a data source from a pre-2020.2 version to Tableau that you have upgraded to 2020.2 (https://www.youtube.com/watch?v=bypr1QPclao), Join only can be done between data that come from the same connection. • Explicitly use a specific join type • Use a data model that supports shared dimensions • Join need to implement row level security Note for E : In Join and Relationship, both can connect to multiple database
