Introduction to Data Modeling for Power BI Video Course
Introduction to Data Modeling for Power BI is an introductory video course about data modeling, which is a required skill to get the best out of Power BI, Power Pivot for Excel, and Analysis Services. The training is aimed at users that do not have a background knowledge in data modeling for analytical systems and reporting.
The goal of the course is introduce the primary concepts of dimensional modeling, using practical examples and demos to illustrate how to obtain the desired result without having to write complex DAX expressions. Creating a proper data model simplifies the code to write and improves the performance. The course is made of 100 minutes of lectures. You can watch the videos at any time and the system will keep track of your advances. Within the course you can download the slides and the Power BI files used in the demos.

Structure Is Good For Beginner

Clear and straight forward introduction to DM.

It was very easy to understand beside the examples are very concrets... thanks.

I found this course good, but it is too basic as expected from an intro course. Overall Marco simplified complex modelling scenarios in digestible piece. Kudos for that. Looking forward to learn more courses from SQLBI team.

Very Informative course.Learned alot of new things.Thankyou!!

As a begginer it was really helpfull for me to understand data modelling concepts.

Very informative, but demonstrates that I will need to learn DAX in order to get more out of Power BI

Most of the topics discussed within this course are interesting. There are some useful tips provided along the way like formatting/preparing your data at source using SQL, SSIS or Custom-M (PowerQuery) as far as possible. Towards the end, some common business scenarios are discussed along with their respective solutions. Overall, it's a good course to realise the importance of Data Modelling in a typical BI Workflow.

Course gave a great overview and insight into data modelling.

The course was great as a refresher. Having taken a course in university on most of this, it was nice to go over it again. I can't speak for those who would hear all of this for the first time. The examples work but maybe could have been easier to follow? I somehow missed what DAX really was until the last couple of lectures. I though I came to learn about PowerBi but instead learned about general analytics. I control the data on the backend so learning about how to manipulate it because it wasn't delivered properly wasn't all that useful but its good to know.

Nice and concise presentation of the importance of setting up the data in the correct way! A wonderful presentation. May I only add that as all users of BI should also have access to Power Query, instead of doing a more complex presentation with advanced DAX coding, an inclusion of PowerQuery would possibly have gotten students a better understanding of the right tools for the job. That would of course have increased the scoop of this excellent free tutorial. I understand why it was excluded.

Thank you. Pretty good.
