  • Patent number: 7640496
    Abstract: A system produces a storage area network resource management report view by obtaining at least one report definition containing report parameters that specify a report layout for presentation of data in the graphical user interface. The system receives a report request to view data in a report view and obtains a data set corresponding to the report request. The data set includes data values to be presented as the data in the graphical user interface. The system applies the data values in the data set to the corresponding report parameters in the at least one report definition to populate the report layout specified by the at least one report definition to dynamically generate at least one report view. The system provides the at least one report view for rendering in the graphical user interface. The system also provides the ability to create custom report views without requiring programming language skills.
