  • List Users

     

    Listing users is described in the above diagram. The user selects a specific criterion from a list of available criteria and passes this to the system. Users corresponding to this criterion are then retrieved from the User datastore and returned to the administrator.

    Reports may be generated based on the aforementioned criteria. This simplification of the system allows for generated reports that correspond directly to the information that the administrator wishes to view. For example, when the administrator selects the criterion that lists users "By User ID", a report can be generated directly from the information that is returned to the administrator simply using the print features of the system.

    The returned status corresponds to the success of the operation. If users are successfully retrieved from the datastore, the status returns Successful. If users corresponding to the selected criterion do not exist, the corresponding error message is returned.
