description
  • Evaluate Arbitrary SPARQL Against an RDF View; In One Query, Some Graphs May Come from Views, Others From Stored RDF; RDF Views Generate a Single SQL Statement, The IRI Generation and IRI Parsing is Only in Selection and Constant Expressions; SQL Has Full Optimization Possibilities and the Generated SQL Does not Depend on Virtuoso Specifics. Hence, RDF Views Are Efficient for Querying Remote, non-Virtuoso SQL Data
