Integrated model management in the data warehouse era

Integrated modeling environments have historically been viewed as extensions of database management systems. Now that the World Wide Web has commandeered the computing landscape, a distributed perspective is required for model management. Our approach to distributed integrated modeling combines a data warehouse of decision metrics, a model warehouse of decision model structural representations, a conversion process to represent models in object-oriented form using the unified modeling language, and component-based software plug-ins which augment typical cross-tabulations analysis with more sophisticated solvers from optimization, statistics, and other modeling paradigms.
