Today, XML is the format of choice to implement interoperability between systems. In this paper we show how heterogeneous data warehouses can be integrated to one federated data warehouse. Using XML as an intermediary representation, adding new systems merely requires the adaptation of mediators that translate between different schemas, queries, and data formats. Our approach was specifically designed for Health Insurance providers who typically want to share some but not all data; moreover maintaining their autonomy regarding the management of access rights and the structure of the data warehouse is essential.
