Which of the following is NOT considered part of a data model?

In the context of Pega Rules Process Commander, a data model is a structured representation of how data is organized, managed, and utilized within an application. It typically encompasses elements such as classes and properties that define the attributes and relationships of the data being handled.

The class rule is fundamental to the data model as it defines the types of objects that can be created and how they are related. Similarly, the property rule defines the characteristics of those objects—essentially the data fields that capture information about each object.

An embedded property defined in the class group contributes to the data model by establishing specific data attributes that are part of different class definitions, allowing for a rich and detailed data structure.

On the other hand, a section rule is primarily a user interface element used to organize the layout of different fields in forms or screens presented to users. While important for the overall user experience and data input processes, the section rule does not directly pertain to the structure, relationships, or management of the underlying data model itself. Hence, it stands apart from the core components that define the data model in Pega.
