A Federated System is a collection of independent, cooperative, possibly heterogeneous and autonomous computer systems (usually database systems) which allows sharing all or some of its data. A Service-Oriented Architecture is an application architecture whose functionalities are defined as independent services which offer transparent communication between physically distributed components, possibly heterogeneous and autonomous. In this context, it is interesting to analyze how a Federated System can be designed within the ideas proposed by Service-Oriented Architectures. This paper presents the design of a Service-Oriented Architecture for Federated Systems. The architecture supports many users sharing data; access control to the data based on access rights which generates many views from a data source, as well as allowing a high automation level for the integration and querying processes. In addition, the bases of a federation's management framework are defined. This framework, as well as the architecture, is validated through an evolutionary prototype towards a completely functional implementation.
