Course Description

Foundations of Data Modelling

Proper data modeling is the foundation of data analysis and creating reports in Power BI. This course lets you explore a toolbox of data cleaning, shaping, and loading techniques, which you can apply to your data.

Diving into Power Query

You'll get to know how to choose between Power Query and Power BI, and discover the foundations of data modeling by going into star and snowflake schemas. You'll apply all of this to real-world datasets issued by the United States Census Bureau.

What you'll learn

  • Differentiate facts and dimensions to design effective star-schema models.
  • Distinguish between star and snowflake schemas and assess their performance impact.
  • Evaluate data model choices that drive accurate insights and fast Power BI reports.
  • Identify essential Power Query transformations for clean, reliable data.
  • Optimize Model and Visual Performance in Power BI

Prerequisites

Introduction to Power BI
1

Defining Tables

Proper data analysis relies on proper data modeling. This first chapter covers the basic concepts and teaches you how to set up and load data from multiple sources.
Start Chapter
2

Shaping Tables

In this chapter, we continue comparing Power Query and Power BI practices. Later, you will exercise combining tables and column extraction on Power BI.
Start Chapter
3

Dimensional Modeling

In this chapter, you'll learn more about one of the most popular approaches to data modeling. You'll get familiar with the basic building blocks of the dimensional model; facts, dimensions, and star schemas.
Start Chapter
4

Star and Snowflake schemas

In this final chapter, you'll continue with an extension of the star schema: the snowflake schema. Lastly, you will have your first practice with performance analyzer in Power BI.

    loved interactive parts the most. i grasp these modelling concepts much better by doing, rather than via watching videos. i can zone out while watching videos, but modelling in practice means i can't zone out.

FAQs

Is this course suitable for beginners in Power BI?

Yes. The first chapter covers foundational concepts like table properties, loading CSVs, and the difference between Power Query and Power BI, so no prior data modeling experience is needed.

What data modeling topics are covered in this course?

You will learn data cleaning and shaping techniques, merging and appending queries, dimensional modeling with facts and dimensions, and both star and snowflake schemas.

What datasets are used in this course?

The course uses real-world datasets from the United States Census Bureau, so you practice data modeling techniques on authentic public data.

What is the difference between star and snowflake schemas, and will I learn both?

Yes. Chapter 3 introduces star schemas with facts and dimensions, and Chapter 4 extends this to snowflake schemas and compares their performance using the Power BI performance analyzer.

Who will benefit most from this course?

Data analysts and BI professionals who work with Power BI and want to structure their data properly before building reports and dashboards.
