Direct Query/Import Mode/Live Connection questions

Hi pennyhoho117 ,
Thank you for your response.

In Live connection, data is not imported into Power BI, it remains in the external data source and data is pre-modeled like SSAS.Where in DirectQuery, data is also not imported into Power BI, it remains in the underlying relational database like SQL Server and it does not require pre-aggregated data in the external system and operates directly with raw tables.

For clear understanding, providing the documents for your reference.
