What is native query in Power BI?

A native query refers to a SQL query that you write directly when connecting to a database. This allows you to control exactly what data is being fetched from the source and can be more efficient because you can filter and manipulate data at the source rather than bringing it all into Power BI and then filtering it.

- Power BI can handle larger datasets more efficiently than Excel, which might struggle with very large data sets.

- Excel is often easier for beginners to start with due to its familiarity and straightforward interface. Power BI, on the other hand, might require some learning for users to fully leverage its capabilities.
