Why would a Data Analyst utilize a blended data source in Tableau?

A Data Analyst would utilize a blended data source in Tableau primarily to combine data from different sources without modifying the original data. This method is particularly advantageous when working with disparate data sources that may be located in different databases or platforms.

Blending allows analysts to create a unified view for analysis and visualization while keeping the original data intact. This approach is effective when there are varying levels of detail within the datasets or when data comes from different systems that cannot directly be joined (like different databases or cloud services). By using a blended data source, the analyst can consolidate relevant information, derive insights, and create visualizations without the need for complex transformations or the risk of altering the raw data.

This methodology promotes data integrity and flexibility, enabling analysts to handle diverse analytical needs while maintaining the original context of the datasets.
