Great course! Recommend it!

Excellent course to understand the main feature on Power BI.Learnt a lot regarding datamodeling concept more in detail. the only setback for me was wish i had done the DAX course first however both of you helped me understand the DAx used and was easy for me go through on this. i would like to have a DM based on cubes too

Great opportunity to improve data modelling and DAX skills. Thanks!

Excellent course. The DAX syntax was a little over my head, but the modelling components really taught me a great deal of how to properly structure project models. My key take away... don't use explicit tables values and always question your data to see if it "really" meets your requirements. There are tons of gotchas explained in this course. Highly recommended.

I really enjoyed this course and understanding the most efficient way to build a model to create business calculations. Particularly enjoyed not only the exercises at the end of each section, but the ability to work through the demonstration examples and then apply to my own models.

Great Course !

Excellent course. Now I have many ideas on how to improve the data models I've been working with!

Simply Awesome! Structured, organised, user friendly, and with good practice step by step. I enjoyed it and learnt a lot, as it is also, super clear to follow and understand.

Great course with only one comment - too bad the last two sections don't have any labs. Luckily I have the book and did the exercises associated with the book. How about incorporating them here?

The course subject and topics covered is really interesting and great explanation. However, it is really frustrating so far as you cannot complete this course unless you know DAX, and I'm not talking about the free dax course, it needs to go higher because it is assumed you understand how dax and each of it's functions work in order to complete each of the tasks/challenges at the end of each module. That was never made clear when buying the course! It should be clearly stated that you should either complete one of the more advanced DAX courses first, or take a quick self test on DAX questions to ensure your level is high enough before buying this course.

• – Hi Robert, we're sorry you feel this way. The purpose of the course is to show what is the right way to create a data model in order to simplify the DAX code required. Most of the DAX code shown in the course is actually what is required in case you do not have a proper data model. Once this first goal is achieved (understanding what is the right data model), then you have to transform the source data in case it doesn't fit the model. There are many tools you can use for that: SQL queries, ETL tools, Power Query (with M language). Sometimes you can use DAX, even though this is not necessarily the best tool for the job, maybe with the exception of some data model based on snapshot tables. Our experience is that knowing the right data model is a very useful skill for Power BI users, even though they don't know data tools and languages and don't want to / cannot spend time to learn them, because they can ask for the data in a proper format from someone else, maybe a co-worker in the company for example. If you want to achieve proficiency in data transformation, you need to use Power Query/M or SQL or other commercial ETL Tools (Informatica, Integration Services, Azure Data Factory, and many others). However, knowing these tools without having a goal (like the star schema we discuss in the course) could lead to models that solve the problem for a specific report and not for a generic semantic model, as a Power BI model can be. We made the choice to show some transformation in DAX because it was the easiest to use and deploy for the examples. The alternative would have required a more complex setup for the data sources, with the risk of losing time with configuration details while the focus should be on the concepts contained in the course. Please, contact us at info (at) sqlbi (dot) com if you want to provide additional feedback about the tools you would have liked to see to perform data transformation. We are always looking for feedback that can help us improve the content. We also hope that this explanation will help other readers that evaluate this course. Thanks!

Great content from basic to advanced concept of data modelling using DAX. Highly recommended for every BI professionals

Perfect methodology and didactics! For sure the best course in the market!

Great course

This is a fantastic course!! I am studying this course concurrently with the Mastering DAX course and I am finding it quite useful to go back between both courses. I am eager to continue in this wonderful journey of learning the DAX language and applying it to my work.
