Abstract: A modeling system for universal specification of user interfaces. The system provides a means for defining user interfaces, including highly complex and dynamic user interfaces, in a manner that is independent of any implementation context. The modeling system leads from a user-friendly visual representation of the user interface, through progressively detailed specifications of structural and behavioral aspects of the user interface parts, until a rigorous definition of the user interface in all its contexts of use is achieved. Using the information captured in the model, tools that automatically generate the fully working user interface code can be built.

Abstract: A computer implemented method for monitoring databases includes providing views for monitoring information associated with a first datacenter and proxy views for monitoring information associated with a second datacenter. The first datacenter receives a query for monitoring information and parses the query to identify filter information that identifies which of the first or second datacenter the requested services are running on. If the filter information indicates the service is running on the first datacenter, the first datacenter queries the views to request the monitoring information from the server on the first datacenter running the requested service. If the filter information indicates the service is running on the second datacenter, the first datacenter queries the proxy views to request the monitoring information from the server on the second datacenter running the requested service, and receives the monitoring information.
