How to configure a Data Source Schema (Data Modeling)

You configure/customize a data source schema by:

  • Renaming data source schema fields
  • Changing data types (what type of data (like text, numeric) the field contains)
  • Changing aggregations (how numeric fields should be summarized)
  • Adding, removing, duplicating or disabling field
  • Adding or editing a description (description of a field)

The data source schema editor is where you configure the data source schema. Here is what this editor looks like:
