## Power BI vs Tableau: Key Differences

Power BI is a breeze to learn compared to Tableau. It lets you make new columns and eliminate unneeded columns, alter data, alter formats and formats, etc. However, Tableau permits working with the data that has been processed. Users can alter the type of data and split columns but cannot eliminate columns that are not needed. Power BI focuses on the "flow" to provide an easy and constant user experience. 

However, Tableau focuses on coding to offer you fresh visual effects that third-party developers develop. Power BI uses DAX for measuring and calculating columns, whereas Tableau employs MDX for dimensions and measures. Power BI offers PowerPivot dots (user to do an efficient data analysis) accessible to users. However, Tableau does not offer this.
