Specific characteristics

Virtuoso is a modern multi-model RDBMS for managing data represented as tabular relations (Tables) and/or RDF sentence collections (Graphs). It is a high-performance, scalable, secure, and open standards-based platform.

Competitive advantages
  • Performance & Scale — as exemplified by DBpedia and the LOD Cloud it spawned, i.e., a decentralized collection of databases that produce a knowledge graph in the cloud that is accessible 24/7 for declarative ad-hoc interactions by both humans and bots using the SPARQL Query Language

  • Engine Sophistication — enables use of SPARQL and an open-standards-based extension to SQL, thereby blending the ACID and scalability features of that language with the semantically-informed navigation capabilities of SPARQL; custom reasoning and inference that brings “explainable AI” to data management and data virtualization

  • Attribute-based Access Controls — fine-grained data access policies informed by entity relationship-type semantics of protected resources and the humans and/or bots seeking access to said resources

Typical application scenarios

Used for —

  • Analytics/BI
  • Conceptual Data Virtualization
  • Enterprise Knowledge Graphs bolstered by Explainable AI
  • Smart & Secure Customer 360
  • Smart & Secure Federated Data Lakes
  • Smart & Secure MDM
  • Smart & Secure Data Services
  • Smart & Secure Data Governance
  • Smart & Secure Data Monetization
  • Safe & Secure Fusion of AI and Data Access, Integration, and Management

— across industries including —

  • Financial Services & Insurance
  • Pharma & Healthcare
  • Bioinformatics and Life Sciences
  • Retail
  • Insurance
  • Government
  • Petroleum (Oil, Natural Gas, etc.)
  • Telco
  • Manufacturing
Key customers

Broad use across enterprises and governments including —

  • European Union (EU)

  • Sanofi
  • GE
  • and many others

— as well as publicly accessible database instances across the massive LOD Cloud, such as —

Market metrics
  • Largest installed-base ​of Multi-Model RDBMS for AI-friendly Knowledge Graphs

  • Platform behind DBpedia

    • DBpedia is an AI- and Query-friendly Knowledge Graph form of Wikipedia

    • DBpedia provided the bootstrap point for the massive Linked Open Data (LOD) Cloud

    • Virtuoso is the platform behind a majority of nodes in the LOD Cloud

  • Performance and Scalability Leader

  • Data Security Leader
