How is a report definition utilized as a data source?

A report definition serves as a powerful tool for generating reports by querying and retrieving a list of data records from the Pega database based on specific criteria set by the user. When used as a data source, it effectively allows you to extract multiple data objects that fit the defined parameters.

The option highlighting this capability emphasizes the comprehensive nature of report definitions, as they are designed to provide a collection of entries rather than focusing on a singular record or making updates. By using a report definition as a data source, users can obtain a broad overview of the data that is mapped in the application, which is essential for reporting and analysis purposes.

Other options revolve around more limited functionalities. For example, returning a single data object or fetching a specific record pertains to querying that may involve different elements, but they do not capture the essence of what a report definition accomplishes. Similarly, updating a data page aligns with processes that focus on data manipulation rather than retrieval, which does not accurately reflect the role of a report definition as a data source.
