But did you know that you can get Power Query to do this for other data sources too? You have to follow some very precise steps to make it happen and even then there are some problems. If you were to load these two tables into the Excel Data Model, you would probably want to create a relationship between the two tables based on the FruitID column.

The technology is essentially the same across all of these products so I will generically refer to Power Pivot in this article.

In the last few years, I and Alberto Ferrari assisted many users of Power Pivot and Power BI who wanted to create their reports using these tools and were struggling with getting the desired numbers from their data. The first approach of an Excel user is to look for a function, or a more complex DAX expression, that can implement the calculation required. Several times, before looking for a correct DAX expression, the problem is defining the correct data model, putting data in the right tables, and creating the proper relationships.

The goal is to teach the concepts, rather than providing formulas to copy and paste. In fact, the reader should try to apply the same ideas to its own data, recognizing the data modeling patterns described in the chapters of the book. We tried to minimize the use of theoretical terms, trying to introduce with very practical examples and design patterns the terminology that is commonly used in data modeling such as fact, dimensions, normalization, denormalization, star schema, snowflake schema, and so on.
