Difference between blending and join in tableau

Question

Accepted Answer

Blending in Tableau combines data from multiple data sources on a single worksheet, while joining combines data from the same data source.

Blending is used when data comes from different data sources, while joining is used when data comes from the same data source.
Blending creates a relationship between data sources on a worksheet level, while joining creates a relationship at the data source level.
Blending allows for combining data without altering the original data sources, while joining requires altering the original data sources.
Example: Blending data from a sales database with data from a customer relationship management system to analyze sales performance by customer segment.
Example: Joining data from two tables within the same database to create a unified dataset for analysis.
