The functional approach was exemplified by the DAPLEX model (34) and is having an impact on object models coupled with functions such as the Iris model, now available commercially from HewlettPackard in their Open ODB system.
The model and language are generalizations of FQL [11] and DAPLEX [40], and have an implementation that fits ideally with the modularity required by extensible database technologies.
