Virtuoso Platform Overview
- 2. The Enterprise Challenge Enterprises are increasingly looking to Data for driving agility via Systems-Of-Intelligence fed by existing Systems-Of-Engagement and Systems-Of-Record. Unfortunately, this pursuit is stifled by the prevalence of Data Silos created by Applications. 2 License CC-BY-SA 4.0 (International)
- 3. A Knowledge Graph Platform that leverages Hyperlinks as “Super Keys” for powerful integration of Data across Disparate Data Sources. Thereby unleashing Data as “a new force” conducted by Hyperlinks that brings the magic behind the World Wide Web to Data Access, Integration, and Management.
