Abstract: A system and method for rule-based asymmetric data reporting having analyst created rules and pre-established rule-based templates. Analysts create data measures together with connection information for the data repository from which the data measures can be obtained. Whenever reports or templates are used with predefined rules, reports are automatically updated with the data measures required. Provisions are made for sparkline integration and e-mail notification. Analysts are able to create spreadsheet reporting without the need for knowledge of formula formatting and insertion.
