True or False:When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the matching fields, then relating these tables is not possible.
Explanation:
Tables that you drag to the logical layer of the Data Source page canvas must be related to each other. When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the matching fields, you will need to select them.
If no constraints are detected, aMany-to-manyrelationship is created and referential integrity is set toSome records match. These default settings are a safe choice and provide the most a lot of flexibility for your data source.

Which of the following are FALSEabout Joins?
Explanation:
According to the official documentation:
Joins are a morestaticway to combine data. Joins must be defined between physical tables up front, before analysis, and can't be changed without impacting all sheets using that data source. Joined tables are always merged into a single table. As a result, sometimes joined data is missing unmatched values, or duplicates aggregated values.
Joins -
1) Are displayed with Venn diagram icons between physical tables
2) Require you to select join types and join clauses
3)Joined physical tables are merged into a single logical table with a fixed combination of data
4) May drop unmatched measure values
5)May duplicate aggregate values when fields are at different levels of detail
6) Support scenarios that require a single table of data, such as extract filters and aggregation
Question 209

True or False:When relating tables, the fields that define the relationships must have the same data type.
Explanation:
According to the official documentation, the following are the requirements for using relationships:
1) When relating tables, the fields that define the relationshipsmusthave the same data type. Changing the data type in the Data Source page does not change this requirement. Tableau will still use the data type in the underlying database for queries.
2) You can't define relationships based on geographic fields.
3) Circular relationships aren't supported in the data model.
4) You can't edit relationships in a published data source.
5) You can't define relationships between published data sources.
6) Your workbook must use an embedded data source for you to be able to edit relationships and performance options in the Data Source page in Tableau Online or Tableau Server.
