What is the main function of a data page in Pega?

The primary function of a data page in Pega is to retrieve and manage data from external sources or databases. This allows applications to efficiently access data that is often needed in various contexts throughout the Pega environment. Data pages act as a centralized source for data, providing a way to ensure consistency and minimize redundancy by caching data in memory. This means that when a data page is referenced multiple times during a user's session, the system can retrieve the data just once and reuse it, improving performance and speeding up application workflows.

In terms of functionality, data pages can retrieve data in real-time from other systems, such as SQL databases or web services, which supports integration with external data sources. They are also capable of managing data in a structured way, making it easier for developers to handle complex data interactions.

While displaying data related to ongoing cases, logging data changes, and compiling reports are important functions in a comprehensive application, these are not the primary responsibilities of a data page. Instead, these tasks may involve other components or tools within the Pega ecosystem that address specific needs for visibility or tracking.
