    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.
