In a Pega application, what is a common use for a keyed data page?

A keyed data page in a Pega application is specifically designed to retrieve and display detailed information related to a specific instance, such as a user or a particular case. By using a key, the data page can efficiently access, store, and return data that is tailored to the individual identifiers provided. This allows for optimized performance since it fetches only the relevant data needed for that instance rather than loading a larger dataset that might not all be necessary.

For instance, if a user is looking for their profile details, a keyed data page can be configured to take the user's unique identifier (like user ID) as input and return the corresponding user information. This targeted approach ensures that the data being accessed is precise and enhances the user experience by providing quick access to the relevant data.

In contrast, the other options presented do not align with the primary function of keyed data pages. For example, displaying a dashboard summary typically involves aggregating data from multiple sources, which is better suited for unkeyed data pages. Presenting a list of case types does not require the specificity that keyed data pages offer, and gathering user preferences for interface customization often relies on different methodologies for capturing such information.
