Working With Tables

Work With Tables

When users see fewer tables, they will enjoy using your data model considerably more. For example, suppose you’ve imported dozens of tables from many data sources and now the visual appears disorderly. In this case, you need to ensure that, before you begin working on building reports, your data model and table structure are simplified.

Configure Data Model And Build Relationships Between Tables

Assuming that you’ve already retrieved your data and cleaned it in Power Query, you can then go to the Model tab, where the data model is located. The following image shows how the relationship between the Order and Sales tables can be seen through the OrderDate column.

To manage these relationships, go to Manage Relationships on the ribbon, where the following window will appear.

In this view, you can create, edit, and delete relationships between tables and also autodetect relationships that already exist. When you load your data into Power BI, the Autodetect feature will help you establish relationships between columns that are named similarly. Relationships can be inactive or active.

The Model view in Power BI desktop provides many options within the column properties that you can view or update.

Under the General tab, you can:

  • Edit the name and description of the column.
  • Add synonyms that can be used to identify the column when you are using the Q&A feature.
  • Add a column into a folder to further organise the table structure.
  • Hide or show the column.

Under the Formatting tab, you can:

  • Change the data type.
  • Format the date.
