Ontotext GraphDB ™ is a database that allows you to link diverse data, index it for semantic search and enrich it via text analysis to build big knowledge graphs. It is preferred by both small independent developers and software architects or scientists at big enterprise organizations because of its visual workbench, data reconciliation and visualization capabilities, open-source plugins for connectivity with FTS engines, NoSQL and SQL databases, virtualization, community and commercial support. GraphDB ™ is one of the few triple stores that can perform semantic inferencing at scale, allowing users to derive new semantic facts from existing facts. It handles massive loads, queries, and inferencing in real-time. There are two editions of GraphDB that can be deployed on-premise or in the cloud: Free and Enterprise. GraphDB Free is non-commercial, file-based, sameAs & query optimizations, scales to tens of billions of RDF statements on a single server with a limit of two concurrent queries. GraphDB Enterprise Edition (EE) is a high-availability cluster with worker and master database implementation for resilience and high-performance parallel query answering.
