We present a method for access to information in remote databases without any prior form of schema integration. The approach is based on the ideas of universal relation interfaces to other data models. Queries are mapped to a universal model which has a minimal structure. Remote systems try to interpret the query in the context of their local schemas. To assist in the selection of possible query interfaces, contextual information is transferred to the remote systems along with the universal queries.
