What does “Data Blending” refer to in Tableau?

Data blending in Tableau specifically refers to the process of combining data from different sources into a single view. This feature is particularly useful when you have related data residing in separate data sets, such as different databases or spreadsheets, and you want to analyze these datasets together.

When you blend data, Tableau enables you to create relationships between the datasets. For instance, if you have sales data in one source and customer information in another, you can blend these two sources on a common field, such as customer ID. This allows you to create visualizations that draw insights from both datasets, enhancing your analysis capabilities without the need for extensive data preparation or combining the data outside of Tableau.

The other concepts presented relate to different aspects of data manipulation and visualization within Tableau but do not accurately capture what data blending entails. Creating calculated fields involves customizing existing data rather than merging multiple sources. Visualizing data on separate dashboards does not imply integration or blending, and extracting subsets of data relates to filtering or segmentation of the data rather than the merging of different sources.
