Hi Sashi,
Virtuoso has its own built in RDF Storage as it is a proven and fully
functional Database with in its own right and thus their is no need for
SQLServer, MySQL or another other remote database for storing the actual
triples/data. They are all stored in the Virtuoso RDF_QUAD table you indicate
below, see:
http://docs.openlinksw.com/virtuoso/rdfandsparql.html
The Virtuoso open source product is currently in use as an RDF store for upto 5
billion triples with acceptable performance, although as a general rule for
with more than 1 billion triples we would advise the use of a Virtuoso
clustered server instance which for vertical and horizontal scaling and
performance, which is only available in the Virtuoso commercial product
offering:
http://docs.openlinksw.com/virtuoso/clusteroperation.html#clusteroperation
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VOSScale
Their are many methods of loading RDF data into Virtuoso which are detailed at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtRDFInsert
For bulk load of large RDF datasets (files) it is recommended the Virtuoso Bulk
loader scripts be use for fast and automated loading of the data as detailed at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtBulkRDFLoader
We have cloud offerings for Virtuoso as an Amazon EC2 AMI as detailed at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtuosoEC2AMI
This includes a prebuilt instance of the OpenLink Data Spaces (ODS) which are a
collection of distributed collaborative applications covering: blogs, wikis,
shared bookmarks, file management, calendaring, email, photo galleries,
discussion forums, polls, and more:
http://ods.openlinksw.com/wiki/ODS/ODSIndex
As well as prebuilt data sets for the DBpedia, Musicbrainz, NueroCommons,
Bio2RDF, BBC Music & programmes or you can simple start an empty Virtuoso
server instance and load your own datasets in the cloud ...
Best Regards
Hugh Williams
