ABSTRACT = {Future information systems will require techniques to integrate data from heterogeneous data sources and provide shared use of operations operating on the data. This paper describes the idea of a mediator architecture to accomplish this.A mediator is a sharable software component placed in a layer between data sources and the applications using them. We briefly describe four classes of mediators and then concentrate on one of them; integration mediators. We give an overview of how integration is usually achieved in current research systems, and how the mediator approach relates to this. Integration mediators have a lot in common with tightly coupled federated database systems.Finally, our plans for a research project to investigate various issues of the mediator approach are outlined. We will initially concentrate on building integration mediators.},
