What is the main responsibility of the Portal Notifications Engine?

The main responsibility of the Portal Notifications Engine is to store information about notifications. This includes tracking when notifications are created, updating their status, and managing their delivery to users. The engine ensures that users receive timely alerts about important events or updates happening within the application. This functionality is critical for enhancing user engagement and ensuring that users remain informed about relevant activities or changes.

In contrast, other aspects like document version control, managing user preferences for portal access, and handling error logging serve different purposes within the application ecosystem. Document version control pertains to maintaining and tracking changes in documents, user preferences focus on individual settings related to their experience within the portal, and error logging is concerned with capturing and recording issues that occur during application processes. While all these functions are important, they do not align with the primary purpose of the Portal Notifications Engine, reinforcing why storing information about notifications is the central responsibility of this component.
