Data integration techniques for use in enterprise architecture modeling

A device for modeling an integrated enterprise includes a first tool for constructing a model of the integrated enterprise and a second tool for analyzing calls, contained in the constructed model, between applications of the integrated enterprise and a database shared thereby. The call analysis tool identifies data attribute imbalances in calls between the applications of the integrated enterprise and the shared database. Data attribute imbalances result if the calls attempt to consume data which was never produced or if the calls produce data which is never consumed. The call analysis tool also generates producer/consumer maps of the data attributes used in the model, producer exception reports which identify data attributes which are consumed but never produced and consumer exception reports which identify data attributes which are produced but never consumed.
