That's definitely an amazing resource – Ferrari and Russo have become experts in explaining practical implementation of data modeling and DAX. If one really wants to get better at Power BI or Power Pivot, a book of that kind can help one understand *the business processes and handle things such as time intelligence, multi-currencies, and inventory logic.
However, there is one piece of advice here: one must **reproduce the examples from this book** using Power BI and develop small projects based on that. It is crucial because many people tend to simply read the book and do not use it to apply the things in practice – it becomes quite hard to answer any questions related to Power BI in a job interview.
In my experience, this book is really helpful when it comes to developing **strong fundamental skills**: structuring the model and other important skills for future work. The reason behind it is quite simple, too: many people are keen on developing visualizations right away, forgetting the backend logic behind everything. If you manage to get the hang of it, your reports will be both beautiful and highly effective and scalable even with a huge amount of data.
One could also try practicing using real datasets such as sales, finance, or inventory scenarios. One could create dashboards where concepts such as date tables, KPIs, and calculated measures will be used – it would help one gain additional experience.
Additionally, one might combine the theoretical learning with practical exercises involving real data and training. In case one needs a structured, professional course that involves concepts of that kind, one might want to visit the SevenMentor's
