    This is the best ideal introductory course on Data Modeling with Power BI I have encountered! Marco and Alberto makes it really easy to understand such complex topics and it trains you as you go along so that once you're finished with the course you have a very strong concept on what proper data modeling is. I totally recommend this course to anyone who is interested in learning "what the heck is" Data Modeling with Power BI. Grazie Mille Marco & Alberto. Cheers from Lima, Perú!.

  • Stef Bols (Oct 10, 2019)

    Great Introduction course, enjoyed it!

  • Simen Schikulski (Oct 7, 2019)

    Might be one of the best video courses I've ever seen. Thank you.

  • Michael Nishimura (Oct 5, 2019)

    Overall, very good. I learned a lot. Star Schema makes sense and examples how to manage around multiple fact tables is helpful. Thanks!

  • Benjamin Kormos (Oct 5, 2019)

    It was great and clear, though the layout of the tables in presentation slides should be the same as in the PBI files for more clarity.

  • Robert Williams (Oct 5, 2019)

    What a fantastic course. I stumbled into a role a few years ago that led me to working daily with SQL and SSRS. I've never looked back and really enjoy working with data, but until now I've never truly understood (and therefore never practiced) the benefits of pushing data models into star schemas. I knew people kept recommending it, but because my last employer and current employer do not have any data warehouse or lakes, I've always just built reporting off the OLTP databases. I get by. But now, even though I know my employer won't fork out the money to put in place a proper data warehousing (and the task will only fall on me which I don't really want) I can at least start putting together a SQL Server data model using views and a new db schema, to suit my needs to improve my data-modelling and report building processes. Thank you so much! Love to see you deliver a course in London (or Hemel Hempstead, Watford, Aylesbury, or near by) one day soon.

    What a very nice course. good to learn from sqlbi

  • Ignacio Barrau (Aug 1, 2019)

    Very nice course. I think it has almost all introduction topics. If I had to add something I would explain what to do when you have a fact table and a chain of conections like Product, ProductSubCategory and ProductCategory. Explain how to model dimensions in that scenario that is very frecuent.

  • Fernando Camargo da Silva (Jul 31, 2019)

    Amazing course, it helps to understand and memorize the basic concepts of data modelling in our mind.

  • Jancarlos Ascencio Acuña (Jul 1, 2019)

    Excelente videos esta informacion no se encuentra asi de facil en otras paginas

  • Shawn Gallagher (Jun 28, 2019)

    Coming from the Excel side, for me this intro was invaluable. Marco has put into words here much of what I had discovered intuitively in getting my dozens of PowerPivot (PP) models to work, over the years, and translated into BI assets to share- so special meaning to me; a real eye opener. This year I began a tech-immersion to really learn Power BI and serious DAX programming since I've had so much fun unleashing my creativity thorugh PP. I am putting this training to good use immediately normalizing the publicly available Medicare data I have begun to work with. I can see how it will help with simplify some complex ranking that I have been struggling with. Also, I will definitely seek more patterns to avoid reinvention. This was great in helping me on my journey - keep it up guys!

  • Andy Stepas (Jun 25, 2019)

    Outstanding introduction!

  • Janderson Macedo Araujo (Jun 24, 2019)

    I am a beginner and this is what I needed to kick off my data modelling journey. Great explanation supported by good examples in a very pleasant narrative. Simply 5 stars!

  • Richard Svensson (May 25, 2019)

    I have followed SQLBI since 2015 and got a lot of good experience from Alberto and Marco. For me it solved a lot of how to think when it comes to what should be done in SQL, Power Query and/or DAX, and especially, what are the pros and cons in different situations. The course is a very good introduction to data modeling using Power BI.

  • JOSE VICENTE DOÑATE (May 24, 2019)

    Sois muy grandes !!!!!!!!!ª

  • Paulo Rocha (May 21, 2019)

    I read "The Definitive Guide to DAX", "Analyzing Data with Power BI and Power Pivot for Excel", attended "Mastering DAX Workshop" with Alberto, "Mastering DAX Videocourse", and the full "Data Modeling for Power BI". All content produced by SQLBI is excellent. I did this intro course as a recap and still learned new insights! Keep up the good work Maestros!

  • Graham Getty (May 4, 2019)

    Best explanation / demonstration of importance of star schemas I've ever seen. As a business user of Power BI, I want to go directly to the visualizations of my data - this course was important reminder to review and optimize the data models as how the data is stored by a data vendor is not always (ever?) the best method for reporting and visualization.

  • Rup Rizal (May 2, 2019)

    Awesome intro. Any PowerBi model and reports I am going to work on in future will definitely focus on modeling and get efficient and simpler DAX measures.
