What distinguishes an install key from a key in terms of hierarchy?

The distinction between an install key and a key in terms of hierarchy lies in their relationship to groups and unique identification within a system. The install key serves as a mapping to groups or collections of related elements, indicating that it is broader in scope. This broader scope allows the install key to encompass multiple items within a specific context or category. In contrast, the key acts as a unique identifier at a specific parent level, which means that it pinpoints a singular item or entity rather than a collection, reflecting a more granular hierarchy.

This framework helps organize data efficiently, allowing for the grouping of related items while still having unique identifiers for individual elements. The hierarchy established through these keys facilitates management and retrieval of data, ensuring clarity in how each key functions within its respective level of classification.
