GraphDB

GraphDB is an enterprise-grade RDF database that unifies diverse data sources through semantic relationships and high-performance SPARQL querying.

GraphDB serves as a robust engine for building large-scale knowledge graphs by strictly adhering to W3C standards like RDF and SPARQL. It distinguishes itself through advanced reasoning capabilities (inferring new facts from existing data) and seamless integration with search tools like Elasticsearch and Lucene. Organizations use it to break down data silos, often achieving sub-second query performance across billions of statements. With native support for Graph RAG and LLM integration, it provides the precise context required for modern agentic AI applications.
