Intranet mediators: a prototype

We describe a mediator designed specifically for an intranet rather than an Internet. Our intranet mediator allows data reconciliation and integration to be completed long before the query is executed. This is because information about the data sources is known and a combined schema can be defined prior to the query. On the Internet, source schemas are not available so integration cannot occur before the query. In our approach, a data warehouse is used for reconciliation of structured data. We propose a new architecture and describe an initial prototype built to test the architecture
