Difference between live connection and direct query mode

Sunkari Another thing to note in difference. Live Connection refers to connecting directly to a Model (SSAS Multidimensional or Tabular) in this regard, all your modeling work is done on those. With Direct Query - you are connecting to a database, and you have the ability to create calculated columns and measures in Power BI. So, Power BI serves as your model layer, while still keeping your data in your databases.
