Riccardo,
D2R is one way to do it, a sort of non-standardised precursor to R2RML.
There are many more ways to do it [1] - that's why we standardise it ;)
Cheers,
Michael (with his RDB2RDF WG co-chair hat on)

FYI...
The RDB2RDF Working Group[1] has published the First Public Working Draft of
R2RML: RDB to RDF Mapping Language[2]. R2RML is a language for describing how
to put relational data on the Semantic Web. With R2RML, people express
customized mappings from relational databases to RDF datasets, allowing them
to view existing relational data in the RDF data model, expressed in their
preferred structure and target vocabulary.
