Abstract :
A general framework is described for achieving interoperability between two database languages, Logres and SOL (Stretch object-oriented language), respectively based on a rule-based and an object-oriented paradigm. A discussion is presented of primitives for exporting and importing data and procedures, distinguishing the export modalities by `copy´ and by `reference´. Several clauses add semantics to the import/export instructions for excluding, renaming, dereferencing, coercing, and unnesting data, for specifying the signatures, and for structuring the output parameters of programs
