OpenLink Software, Inc., is pleased to announce the latest update of Virtuoso, its modern multi-model relational database management and conceptual data virtualization platform.

For many years, Virtuoso has provided a secure, cross-platform, high-performance, massively-scalable, and cost-effective solution for cognitive management, integration, and creation of public and/or private semantic webs of linked data (i.e., conceptual entity relationship graphs over disparate data sources).

Maintenance Release 8.1, focused primarily on bug fixes and secondarily on interface tweaks to aid better understanding of existing functionality, builds on Virtuoso 8.0’s key innovations aimed at the natural fusion of artificial intelligence with data diversity, with particular focus on Digital Transformation to leverage Data Analytics, Data Virtualization, Data Flow, and Sophisticated Data Security.
