With respect to the state of the art in XML database engines, there are several that go beyond XML storage and XQuery processing. Among the native XML database engines, eXist is notable for an XQuery extension for SQL processing. But several platforms are distinct for operating with multiple types of data (SQL tables, XML documents, RDF triples, user-defined types) and multiple query languages (SQL, XQuery, SPARQL). Included in this group are IBM DB2, Oracle 11g and OpenLink Virtuoso. Last month Microsoft jumped in with a patent filing for RDF processing: RDF STORE DATABASE DESIGN FOR FASTER TRIPLET ACCESS "In consideration of the above-described deficiencies of the state of the art, the invention provides RDF store database designs and efficient techniques for converting SPARQL queries to SQL queries, related systems, and methods that are practical, can provide faster triplet access, and which can reduce the computational overhead and cost associated with storing large volumes of RDF metadata." Are there other servers or engines, perhaps in academia, that support SQL, XPath, XQuery and SPARQL queries of tables, documents and RDF triplets? ________________________________________________________________________ Don't let your email address define you - Define yourself at http://www.tunome.com today!
