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.

Data modeling and table properties

Power Query vs. Power BI

Load and transform data

Loading a CSV

Rounding, replacement, and sorting

Data categorization and visibility

Working with string columns

Defining 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.

Facts vs. dimensions

Creating a star schema

Splitting data into facts and dimensions

Load a new dimension

Create another dimension

Dimensional Modeling

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.
