Combining tables using calculated columns
To begin working with calculated columns, we'll make a modification to the Tabular Model design created in the previous chapter. In a business intelligence solution, we often combine data from multiple source tables to simplify the structure and make it easier for users to navigate and report on information. Previously, we used a T-SQL query to join the Product Subcategory and Product Category table information to populate a single table in the semantic model. To gain experience with a different table design technique and develop new skills, we will change the approach.
Getting ready
You're going to make a design modification to the Tabular Model you created in Chapter 9, Using Tabular Models. If you would like to keep that project in its current state for reference, you can make a copy of the project folder for backup purposes. Otherwise, we'll just pick up from where we left off and continue to work in the same Tabular Model.
