Are you hoping to improve your Power BI reports and dashboards by creating better data models? I recommend you check out Expert Data Modeling with Power BI, Second Edition, by Soheil Bakhshi.What I Liked Best1. Offers selection of both breadth and depth of Power BI topics – I think this is a great primary reference for Power BI as it offers both a breadth of topics, from foundational to advanced, as well as some depth on more advanced topics. If I wanted to know what DAX is, this book offers that definition. It assumes you know the basics and addresses some more intermediate and advanced situations for writing DAX (virtual tables, time intelligence functions, aggregations, calculation groups). There are books available to gain basic knowledge of DAX (the Other Books You May Enjoy section in the Appendix offers some)2. an in-depth introduction to Power Query – Power Query is the module I use most, and I found the chapters and sections on Power Query offered new information and understanding, notably understanding the different connection modes and Soheil’s explanation and examples for using query parameters and custom functions. These are some of the clearest examples of I’ve seen for using query parameters and custom functions.3. Examples showing the application of data warehousing concepts applied in Power BI – I appreciate how the author showed how to use the features of Power BI holistically across Power Query and DAX to build a data model using data warehousing best practices. From building out the dimension tables in Power Query to setting up the relationships in model view and writing DAX measures to enhance the model, Soheil walks through the entire process clearly and concisely.If you’re looking for a book that combines data modeling best practice as applied using Power BI, Expert Data Modeling with Power BI by Soheil Bakhshi is a go-to resource.Thanks to Packt for offering me the opportunity to review this book.

Lukesh larik Jun 04, 2023

I went through the book, and it helped me in understanding, how data models are structured in Power BI with great clarity. As I went through the different chapters of this masterpiece, I got to learn how in a better way we can deal with schemas, tables,s and data structures so that we can make our data model more lean and efficient.

Devaraj Jul 01, 2023

Anyone looking to improve their data modelling abilities with Power BI should check out "Expert Data Modelling with Power Bi." The book offers a thorough manual for improving data models for improved reporting and business requirements. It is filled with useful examples and is appropriate for readers of every skill level, from beginners to specialists, in my opinion. However, I advise that you have at least a month of comfortable Power Bi working experience before buying this book.The book introduces users to new features, choices, and DAX functions while also covering subjects including security, sophisticated data modelling techniques, and data preparation. For data analysts who frequently use Power BI, it is a useful resource because it is well-structured and simple to understand.

Brady May 31, 2023

This book is an invaluable resource for anyone looking to excel in the world of Power BI. As an experienced BI developer, I was impressed by the author's deep exploration of data modeling, data warehousing, and the significance of establishing a solid data structure right from the start.Throughout the book, Bakhshi provides practical tips and best practices that help optimize performance and reduce complexity in DAX expressions. As someone who has struggled with performance issues in the past, I truly appreciate the author's emphasis on creating efficient models that align with business requirements and minimize maintenance costs. Great reference to have on hand before diving into a project.
