Abstract
Federated information systems integrate various heterogeneous autonomic databases and information systems. Queries respect to the federation have to be translated into the local query language and must be transformed with respect to the local data model. This paper deals with the problem of a global query according to an object-relational federation service. This SQL query is to be translated into an equivalent XQuery expression, so that it can be processed by the corresponding XML component database system according to the local schema.
