An Approach to Behavior Sharing in Federated Database Systems
Doug Fang, Joachim Hammer, Dennis J. McLeod · 1992
An approach and mechanism to support the sharing of behavior among the component database systems in a federation is described. In the context of a functional object-based database model, a technique to support intercomponent behavior as well as inter-component information unit sharing is presented. An experimental implementation of the behavior sharing mechanism and algorithms is examined, and its practical utility and effectiveness are assessed. This work is couched in the framework of the Remote-Exchange research project and experimental system. 1 Introduction A principal goal of the current Remote-Exchange research project at USC is to provide a comprehensive mechanism for the transparent sharing of objects among autonomous components in a federation of database systems. In addition to the sharing of instance and type objects [ Fang and McLeod, 1992 ] , behavior sharing constitutes the third aspect of intercomponent information exchange that is cur- rently under investigation.
