How does Virtuoso handle different data models?

Virtuoso is a multi-model RDBMS that natively handles data organized as relational tables and/or RDF statements, which can be represented as graphs or in notations like Turtle, JSON-LD, and RDF-XML.

Can I use existing database tools to access Knowledge Graphs with Virtuoso?

Yes, Virtuoso allows you to use standard ODBC, JDBC, ADO.NET, or OLE DB connections from existing applications to access both local and public Knowledge Graphs like DBpedia and Wikidata.

What is Conceptual Data Virtualization in Virtuoso?

It is the ability to use SQL and/or SPARQL to combine data across different databases conceptually, creating richer information dashboards that are informed by ontologies for Explainable AI.

How does Virtuoso address data privacy?

Virtuoso uses Profile Knowledge Graphs to declaratively inform data access policies based on Attribute-based Access Controls (ABAC), enhancing privacy and security for applications like digitally signed emails.

Can Virtuoso replace traditional database diagrams?

Yes, it allows you to replace static design diagrams with functional Entity Relationship Model Graphs that manifest as a live Knowledge Graph, without sacrificing performance, security, or platform independence.

How can Knowledge Graph construction be simplified with Virtuoso?

Virtuoso simplifies Knowledge Graph construction through familiar user interactions, such as using a browser extension to bookmark web resources, which automatically generates structured data.

What kind of terminology tools can be built with Virtuoso?

You can build powerful, live terminology glossaries that are published as Linked Data, which significantly aids in information discovery and knowledge sharing within and beyond an organization.

Does Virtuoso support both SQL and SPARQL?

Yes, Virtuoso is a polyglot system that supports both SQL and SPARQL queries, often within the same query, enabling seamless integration between relational and graph data.

What is the benefit of using Linked Data principles with Virtuoso?

Using Linked Data principles allows Virtuoso to create powerful Knowledge Graphs that break down data silos, enabling seamless data flow and fostering enterprise agility and digital transformation.

Is Virtuoso limited to on-premise deployment?

No, Virtuoso is available for on-premise installation on Windows, Linux, and macOS, and is also offered as Pay-As-You-Go (PAGO) and Bring-Your-Own-License (BYOL) editions on cloud platforms like AWS and Microsoft Azure.

What is a 'polyglot' system in the context of Virtuoso?

A polyglot system like Virtuoso can store, manage, and query data in multiple models. It supports both relational (SQL) and graph (SPARQL) data, often within a single query.

How does Virtuoso relate to the Semantic Web?

Virtuoso is a key technology for the Semantic Web, as it provides the infrastructure to host, manage, and query RDF data, which is the foundation of Linked Data and the Semantic Web.

What are Attribute-based Access Controls (ABAC)?

ABAC is a security model where access rights are granted to users through policies that combine attributes. Virtuoso uses this to create sophisticated, declarative data access policies.

Can Virtuoso be used to create Explainable AI (XAI) systems?

Yes, by using ontology-informed Knowledge Graphs, Virtuoso enables the creation of AI systems where the reasoning behind decisions is transparent and can be queried, which is a core principle of XAI.
