In Pega, which class contains the data objects for the application?

The data class is fundamental in Pega as it is specifically designed to handle data records and objects used within the application. It serves as a repository for entities that represent the information necessary for the application, such as customer records, product details, or any other data-centric elements. By organizing data into classes, Pega allows for efficient management, reuse, and retrieval of data across the application.

Using the data class helps in promoting a clear structure within the application, distinguishing between operational tasks (which are typically associated with the work class) and data handling, making it easier for developers to maintain and develop their applications effectively. This is crucial for applications that require data-driven functionality.

While other classes serve their specific purposes—such as the work class which focuses on the processing of tasks, the integration class for managing integrations with external systems, and the service class for handling service requests—none of those are specifically dedicated to managing data objects. Thus, the data class is the correct answer because it is the designated class for containing and processing the data objects essential for the functioning of a Pega application.
