Alteryx Advanced - Blending

The video tutorial explains how to combine data sources using Alteryx tools, focusing on Join and Union tools for database workflows. It covers the Join in DB tool for combining database data streams, the Data Stream In tool for integrating external data, and the Union INDB tool for merging data streams. The tutorial provides step-by-step instructions and configurations for each tool, emphasizing the importance of matching data types and understanding join types.
