"Linked Data Views" (formerly known as "RDF Views") over Native SQL Data Sources enable Virtuoso to expose pre-existing internal relational data as Virtual RDF Graphs thereby exposing such data to SPARQL query access, both directly and via Virtuoso's built-in support for SPARQL-in-SQL (SPASQL). The entire process results in RDF Data sets and optimized data access without physical regeneration of RDF Data Sets from the originating SQL Data.
