Key Features

  • Understand data modeling techniques to get the best out of data using Power BI
  • Define the relationships between data to extract valuable insights
  • Solve a wide variety of business challenges by building optimal data models

Book Description

Microsoft Power BI is one of the most popular business intelligence tools available on the market for desktop and the cloud. This book will be your guide to understanding the ins and outs of data modeling and how to create data models using Power BI confidently. You'll learn how to connect data from multiple sources, understand data, define and manage relationships between data, and shape data models.

In this book, you'll explore how to use data modeling and navigation techniques to define relationships and create a data model before defining new metrics and performing custom calculations using modeling features. As you advance through the chapters, the book will demonstrate how to create full-fledged data models, enabling you to create efficient data models and simpler DAX code with new data modeling features. With the help of examples, you'll discover how you can solve business challenges by building optimal data models and changing your existing data models to meet evolving business requirements. Finally, you'll learn how to use some new and advanced modeling features to enhance your data models to carry out a wide variety of complex tasks.

By the end of this Power BI book, you'll have gained the skills you need to structure data coming from multiple sources in different ways to create optimized data models that support reporting and data analytics.

What you will learn

  • Implement virtual tables and time intelligence functionalities in DAX to build a powerful model
  • Identify Dimension and Fact tables and implement them in Power Query Editor
  • Deal with advanced data preparation scenarios while building Star Schema
  • Explore best practices for data preparation and data modeling
  • Discover different hierarchies and their common pitfalls
  • Understand complex data models and how to decrease the level of model complexity with different data modeling approaches

Who this book is for
