Negotiation in organizational DSS using extended relational views

Presents a novel approach to views in relational databases that supports the negotiation process and monitors incremental changes in the groups´ positions. The common body of information is stored in a relational database. A view augmented with a differential file is called an independently updated view (IUV). Each group has a different IUV that corresponds to its particular position in the negotiation. An IUV can be updated without any restriction on the type of view, nature of updates to the view, or updatability of the database. Updates are stored in the differential file. To allow IUVs on dynamic databases, a mechanism is described that maintains consistency between the database and the IUV
