The record

Purpose: Stardog connects enterprise data into a semantic layer for AI, analytics, search, and applications.
Virtualization: Virtualization accesses disparate on-premises or cloud data without moving or copying it.
Inference: The Inference Engine applies business rules at query time and displays the logic behind results.
AI features: Stardog Voicebox uses large language models for knowledge-graph modeling, maintenance, and query writing, while built-in machine learning provides similarity search and predictive analytics.
Data quality: Stardog supports SHACL constraints to validate data and flag inconsistencies across data silos.
Standards: The platform supports SPARQL, SPARQL*, GraphQL, and W3C RDF standards.
Scale: The graph database supports up to 100 billion data points per installation and scale-out deployments up to 1 trillion triples.
Integrations: Connectors cover databases including Snowflake, BigQuery, Oracle, PostgreSQL, MongoDB, Elasticsearch, Salesforce, Jira, Splunk, and REST sources.
BI support: Officially supported BI tools include Tableau, Power BI, cumul.io, Apache Superset, Siren, IBM Cognos, Metabase, and RapidMiner.
Deployment: Stardog can run as a managed AWS cloud service, in customer cloud environments, or on premises through Docker, Kubernetes, AWS Marketplace, and Azure Marketplace.
Security compliance: Stardog publishes a SOC 2 Type I report covering controls relevant to systems containing Stardog Cloud customer data.
Support: Enterprise licenses include base support, a dedicated Customer Success representative, and access to Solutions Architects.
Free-plan limitation: Stardog Free is available for commercial use but excludes high availability, caching, backups, LDAP integration, and the full breadth of Connectors.
