“At its core, Power BI functions best when you have data models that are well-designed and optimized. Whether a reader is new to Power BI or has been working with tabular models for a while, this book is both a strategic guide and a collection of tangible examples for data modelers of any skill level. Soheil goes beyond the basics of dimensional modeling, Power Query, and DAX to delve into detail about comprehensive model design and deployment. Modeling approaches in this book take advantage of current functionality in Power BI and are enriched with great examples using community tools like Tabular Editor and DAX Studio. This is a book I’ll reference for years to come.”—

“Power BI enables developers to get started quickly in building data models but they often encounter challenges ranging from the scale of source data, the integration and quality of source data, and the complexity of security and analytical requirements. This book provides a rich set of examples and practices to address these challenges and also highlights the latest modeling features including aggregations, incremental refresh, and composite models. As Power BI datasets (models) remain at the center of Power BI solutions, I’d strongly recommend this book for Power BI developers to help take their modeling skills and solutions to a new level.”
Brett Powell – Author of Mastering Power BI & Microsoft Power BI CookBook, Owner and BI Consultant at Frontline Analytics
“This book can give you the expertise you need in Power BI to effectively streamline the way you work with data and perform reporting.
Soheil does an incredible job at detailing not only all the steps involved in data modeling but also the concepts and how they can be implemented in the real world. I personally like the vast array of images that offer immersive insights into concepts, making it much more easier to understand techniques and visualize how things work.
I recommend this Power BI book for anyone who wants to use the tool more confidently and gain value from business data. While this book equips you with data modeling skills, it also makes for an engaging read. I particularly enjoyed reading the book, and even learned some new skills along the way.”—
