Excellent book for data modeling with Power BI and Power Pivot You can really waste a ton of time with DAX measures if your model is a mess to start with. This book does an AWESOME job of explaining how to properly set up your model, which makes creating visuals and measures much much easier.Wonderful Read; Read Prior Book First Though Wonderful read; you will get ALOT out of it.I would recommend reading "The Definitive Guide to DAX" first so that some of the model building equations make sense.I have already applied many techniques and thought processes into my models.Thank you Alberto Ferrari and Marco Russo!Not Helpful to a Business Professional Data End User This book did not meet my particular needs, though I think it is fine for a different audience. Although the book's title contains the words "Power BI" and "Power Pivot", it is really a primer on how to structure a relational database. I am a business professional who is highly conversant with both Excel and Access. I am not, however, the person who is responsible for laying out all the data tables. I sometimes need to take data from multiple sources and perform analysis which I want to visualize. I bought the book hoping to get insight into how to take my existing analyses and create awesome Power BI visualizations with only modest modification of the underlying data structures. This book did not meet that need. I'm headed back to youtube for that kind of tutorial.
