[Data Modeling] Dynamic class references (DCR) are one approach to creating a data model in a Pega implementation. Which one of the following best…

Dynamic Class Referencing (DCR) is a Pega Platform feature that enhances data model flexibility by deferring the specification of a page's class until runtime. Instead of hard-coding a concrete class at design time, a developer can configure a page property to resolve its class dynamically based on the value of another property, a data transform, or other conditional logic. This allows a single set of rules to operate on different types of data objects, which is essential for building reusable framework components that can be adapted to various implementation-specific data structures without modification.

B: This describes standard data modeling associations (e.g., page lists, embedded pages), not the specific mechanism of DCR, which is about runtime class resolution.

C: DCR determines the object's entire class structure at runtime, not just its attributes. Adjusting attributes on a page of a fixed class is a standard operation.

D: This describes static class referencing, the direct opposite of DCR. DCR is used precisely when the class is not predefined and needs to be changeable.

1. Pega Documentation

"Creating a flexible data model with Dynamic Class Referencing": This document states

"Dynamic Class Referencing (DCR) allows you to create a more flexible data model by dynamically determining the class of a page or page list at run time

instead of design time." This directly supports the core concept in option A.

2. Pega Documentation

"Data models": In the section on data modeling best practices

DCR is highlighted as a technique for reusability. It explains that the class of a page is determined at runtime

often based on a parameter or property value

which aligns with "based on user input or certain conditions."

3. Pega Documentation

"Configuring a dynamic class reference": This guide details the implementation steps

showing that the page's class is set to "refer to a property" or "refer to a data page

" confirming that the class is resolved dynamically based on runtime data

not a fixed design-time definition.
