It’s obvious that this book covers all the concepts of data Modelling from converting from OLTP to Star schemes, Relationships, Time Dimensions, Multiple fact-tables, data granularity management, SCDs, etc... to name a few... But, the best part is that, this book is dealing with all the concepts in a very practical way and now when somebody tells me about a dashboard or report requirement, the data model is coming to my mind. It has given me the confidence that I am modeling it the right way and following the best practices. After reading this book, I am able to figure out the best method to create various datasets in PowerBI that will give the right amount of analytical power at optimum performance.
One should not touch Power BI without reading this book!!!! It will definitely save time. Definitely recommended.
