Abstract
This paper discusses the negotiation and support of interdependent data in federated database systems. We present extensions to SQL that are used for negotiating distributed interdependent data, and we use quasi-views (a concept similar to quasicopies and distributed materialized views) to support the interdependent data that is negotiated. The emphasis of our work is on a method that scales well to federations that have many component systems and are very geographically distributed.
