The present invention is directed to a method and system that includes comparing first and second models. A comparison model may be generated that indicates differences between the first model and the second model. A notification manager is used to register the comparison model as a subscriber of the first and second models. The first model is updated to reflect a first designated change. Upon successful completion of the first designated change, the notification manager is used to issue a notification of the designated change to the first model. At least the comparison model is updated to reflect the first designated change, and the comparison model is displayed on a client.
