What is the difference between Power BI and Tableau?
Both connect to data, let you shape it, and turn it into interactive dashboards. The differences sit underneath. Power BI is Microsoft's tool: you model data in a star schema, write calculations in DAX, clean data in Power Query, and publish to the Power BI service inside Microsoft 365. Tableau is Salesforce's: you connect and blend sources, write calculated fields and level-of-detail (LOD) expressions, and publish to Tableau Server or Tableau Cloud. Power BI leans on the model; Tableau leans on the visual.
