Overview of this book

This book is a comprehensive 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 to gain deep and detailed insights about your organization. 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.

Section 4: Advanced Data Modeling

This section focuses on advanced data modeling techniques that you may not deal with on a daily basis but are extremely important to know about. Implementing parent-child hierarchies, dealing with different calculations in a hierarchy, using aggregations, different ways to handle many-to-many relationships, along with more advanced business requirements to be implemented in the data model are all covered in different chapters of this section. You need to have a deep understanding of the star schema and DAX. Like other parts of this book, the chapters of this section are fully hands-on with real-world scenarios.

This section comprises the following chapters:

Chapter 10, Advanced Data Modeling Techniques

Chapter 11, Row-Level Security

Chapter 12, Extra Options and Features Available for Data Modeling
