Power BI Tutorial For Beginners | Edureka

Forty hours of Power BI from edureka!, and the longest course on this subject carried here.

The length buys repetition rather than breadth, which for a tool like this is the right trade: the same operations appear again in a new context until they stop needing to be looked up. It starts at installation and the difference between Power BI Desktop, Service and Mobile, then works through connecting to data, cleaning it in Power Query, and the modelling decisions that make a report either fast or unusable.

DAX gets a long stretch of its own — calculated columns against measures, the filter context that explains why a total does not match what the eye expects, and the time-intelligence functions every real report eventually needs.

Recorded as separate sessions, so it works as a reference once watched.
