Upon receiving a request for a user interface view from a user interface, a user identity and a user authorization class for a user of the user interface can be checked against a user registry and an authorization class registry, respectively. A user interface view component can be retrieved according to the user identity and the user authorization class. The user interface view can be generated by aggregating the retrieved user interface view component with at least one other user interface view component consistent with the user identity and user authorization class, and the generated user interface view can be returned for display to the user via the user interface. Related systems, articles of manufacture, and computer-implemented methods are described.
