---+++ 2013-04-24 -- Virtuoso 7.0 Unleashed!
Virtuoso 7.0 is a game-changing hybrid RDF & SQL Column-Store
DBMS for handling Big Data challenges associated with --
* cost-effectiveness -- as result of new column-store
data compaction technology
* performance -- array (vectorized) execution of queries
across multiple threads per CPU core
* scalability -- scale from multiple instances of Virtuoso
per machine to multiple instances per collection of machines
in a shared-nothing cluster
* security -- use fine-grained access control lists (ACLs) and
data access policies that are driven by entity relationship
semantics to control data access
* heterogeneous data integration -- merge data across a wide
variety of data sources extending from existing SQL RDBMS
systems to file servers and Web services.
