What was missing in the destination schema that necessitated a new field group creation for a cross-channel relationship?

Creating a new field group for a cross-channel relationship often stems from the need for a dedicated reference that can accurately connect the various data sources involved. In this case, having a dedicated string-type field as a reference is vital because it allows disparate systems or platforms to recognize and reconcile customer data consistently.

This string-type field acts as a common identifier, linking records across different channels. When working with various sources of customer interactions, it’s crucial to establish a unified reference point so that data combined from multiple origins can be accurately matched and utilized. Without this dedicated string-type field, the ability to create meaningful connections in the data becomes limited, potentially leading to fragmented customer profiles and ineffective marketing strategies.

Other types of fields, such as numeric identifiers, timestamp fields, or user feedback fields, may serve different purposes but do not fulfill the specific requirement of creating a reliable reference for cross-channel relationships. Therefore, the creation of a dedicated string-type field directly addresses the need for cohesive data integration across various channels, justifying its necessity in the destination schema.
