Abstract: A system may determine metadata information associated with data included in a data structure. The system may identify a category, associated with the data, based on the metadata information. The system may present, for display, a user interface that allows a user to build a graphical query based on the category. The graphical query may include a user-defined visual representation of a data structure query associated with the data. The system may receive information associated with the graphical query based on presenting the user interface. The information associated with the graphical query may be received based on input provided via the user interface, and may include information associated with the category. The system may provide the information associated with the graphical query.

Abstract: An approach provides service assistance using a hierarchical order of communication channels. Service requests are received from a user. A plurality of different modes of communication functionality can be made available for interactivity with the user. A hierarchical order of the modes can be established in relation to the respective degree of communication interactivity. The mode of least degree of communication interactivity in the hierarchical order can be selected for initial communication with the user in response to the request for service. After communicating with the user in accordance with the selected mode, communication with the user can be changed to a communication mode higher in the hierarchical order if the service request has not been resolved.
