DAX Optimization and Performance

Overview

DAX can seem simple when just learning but then gets progressively more difficult and it is very hard to master. There are so many subtilties.

This makes trying to figure out why your DAX code is underperforming, and fixing it, overwhelming at times. This course attempts to make this process easier.

The course starts with the importance of proper data modeling and why a Star schema is so critical. We then cover the concepts of normalization and denormalization along with the use of dimension and fact tables.

We cover in depth the importance of using the VertiPaq Analyzer when exploring the makeup of your data model.
