Power BI DAX Training Course

Learn the fundamentals of DAX on our One-Day Course

Power BI is a powerful tool. Users can achieve quite a lot without much DAX knowledge but to take your skills and modelling ability to the next level, fundamental understanding of the DAX language is key. Our one-day course will introduce key concepts and work through exercises so students leave with a clearer picture of how to write DAX. You will learn:

  • To write DAX functions and understand expressions
  • use tools to help manage and create DAX
  • create complex expressions 
  • learn methods to optimise expressions and more
