Combine database and flat file data in Tableau by connecting to both data sources separately and using data blending or relationships to integrate them based on common fields.
Practical Response 1:
“To combine database and flat file data in Tableau, I connect to both sources independently, then use data blending with a common dimension like Customer ID or Date to link them together in my analysis.”
Practical Response 2:
“When I need to combine database and flat file data in Tableau, I establish separate connections to each source and create relationships through shared fields, allowing me to build visualizations that pull from both the database tables and flat file simultaneously.”
Detailed Explanation:
Combine database and flat file data in Tableau using these approaches:
Data Blending Method: Connect to your database as the primary source and your flat file (Excel, CSV) as secondary. Tableau automatically detects common dimensions and creates blend relationships, indicated by orange chain links. This method maintains the flat file as a supplemental data source.
Relationship Method: Use Tableau’s relationship feature by dragging both database tables and flat files into the canvas, then defining relationships based on common fields. This creates a more integrated data model without traditional joins.
Cross-Database Join: For supported databases, you can directly join database tables with flat files that have been imported into Tableau’s data engine, treating the flat file as another table in your data model.
The key to successfully combine database and flat file data in Tableau is ensuring you have common dimensions (like IDs, dates, or categories) that can serve as the linking mechanism between the different data sources.
