What does the flatten transformation do to hierarchical data?

The flatten transformation is specifically designed to take hierarchical data, which exists in a multi-level structure, and convert it into a single-row format. Hierarchical data often consists of nested elements, making it complex to analyze. By flattening this data, it’s reorganized into a flat table where each record corresponds to a unique entry, eliminating the levels of hierarchy.

The process is crucial when working with databases or datasets that contain relationships or dependencies among data points, as it simplifies the data structure, allowing for easier manipulation, reporting, and analysis. This transformation is particularly valuable in CRM analytics, where the ability to easily access and analyze customer interactions and relationships can lead to more informed decision-making.

The options that involve aggregation, filtering, or enhancing do not accurately describe the primary function of flattening, which focuses solely on restructuring data from a hierarchical format to a more straightforward, one-dimensional one.
