Table by Reference in Power BI allows users to create a new table by referencing an existing one, maintaining a connection to the original data source. This method ensures that any updates or changes made to the source table automatically reflect in the referenced table. Merge Query in Power BI enables combining data from multiple tables based on a common column. Users can perform inner, outer, left, or right joins to merge tables, facilitating comprehensive data analysis. Utilizing Merge Query enhances data modeling and visualization capabilities within Power BI, empowering users to extract valuable insights from diverse datasets efficiently.
