Abstract

Customizing Enterprise Information Systems (EIS) scale applications can be very expensive, also incurring additional costs during their lifecycle when customizations may need to be re-engineered to suit each EIS upgrade. The ongoing development of a temporal meta-data framework for EIS applications seeks to overcome these issues, with the application logic model supporting the capability for end users to define their own supplemental or replacement application logic meta-data, as what the authors term Variant Logic, to become a variation of the core application logic. Variant Logic can be applied to any defined model object whether visual objects, logical processing objects, or data structures objects. Variant Logic can be defined by any authorized user, through modeling rather than coding, executed by any user as an alternative to the original application logic, and is available for immediate execution by the framework runtime engine. Variant Logic is also preserved during automated meta-data application updates.
