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.

    Excellent learning

  • Baruc Nino (Apr 4, 2020)

    I liked this course. You gave me an important overview of a Data Modeler for Power BI.

  • lemuel llanza (Apr 3, 2020)

    i loved it. very well explained and i love the different scenarios that are presented along with the solution. I have already recommended this free course to some of my friends and if only i could afford the other course ill probably will buy it as well. thank you so much for this.

    Excellent!

  • Nicolas Lope de Barrios (Apr 1, 2020)

    This was great as an introduction to data modeling, although is clear that is intended for Power BI users, it would be great if you talked a bit about avoiding design problems in the data source (i.e creating a tabular model in SSAS). It clearly states the importance of the star schema and good design.

  • Fran Macias Rodriguez (Mar 31, 2020)

    Very interesting. I have learnt many concepts unknown for me.

  • Sérgio Santos (Mar 30, 2020)

    Excelent introduction to data modeling, with some clear examples and good auxilary materials.

  • Cristian Cheij (Mar 29, 2020)
