Power BI Masterclass - Data Modelling - How to Create Dynamic Hierarchies

The video tutorial explains how to create a dynamic hierarchy in Power BI. It begins with modifying the orders table and preparing data by unpivoting columns. The tutorial then demonstrates using a matrix visual to display hierarchy data and introduces the concept of a dynamic hierarchy. It concludes with final steps and tips for creating a dynamic hierarchy, emphasizing the importance of data preparation and the use of slicers for filtering.

What is the first step in creating a dynamic hierarchy?

• Deleting unnecessary data

• Adding a new column

• Creating a new data model

• Modifying the orders table

Why is an index column added during data preparation?

• To assist with the unpivoting process

• To sort the data alphabetically

• To filter out unnecessary data

• To create a backup of the data

What should be ensured about the hierarchy table before proceeding to create visuals?

• It is exported to a new file

• It is duplicated

• It is not connected to the data model

• It is connected to the data model

What is the purpose of using a slicer in the visual?

• To add more data

• To filter data dynamically

• To create a new hierarchy

• To delete unnecessary columns

What is the main feature of a dynamic hierarchy?

• It creates a new data model

• It enables hierarchical filtering

• It automatically updates data

• It allows multiple selections

How can a second hierarchy table be created?

• By importing a new dataset

• By exporting the existing table

• By using a DAX expression

• By manually entering data

What is the relationship type used between the two hierarchy tables?

• One-to-many

• Many-to-many

• None

• One-to-one

Why is a single direction filter used between the hierarchy tables?

• To simplify the model

• To ensure correct filtering

• To prevent data duplication

• To allow data flow in both directions

What issue arises if the amount and sales are taken from the first hierarchy table?

• Data is deleted

• Data is duplicated

• Data is not filtered correctly

• Data is not displayed

What is the benefit of using a dynamic hierarchy in reports?

• It simplifies data entry

• It reduces data size

• It allows for static data views

• It enables flexible data analysis
