GraphDB Free edition is a fully functional member of the GraphDB family. Its only limitation is that it can handle no more than two queries in parallel. GraphDB Free is appropriate for systems that require massive volumes of data, as it applies no constraints on the volumes of loaded data. It includes all the advanced features of GraphDB that make it more than a plain RDF triplestore and put it ahead of the competition: patent-pending inference implementation, geo-spatial indices, owl:sameAs optimization for more efficient integration of linked data, comprehensive full-text-search integration and many others.
GraphDB Free is a perfect starting point for smart data proof-of-concepts and for projects that require an on premise or embedded semantic graph database (cloud options are also available). Although GraphDB Free meets production deployment requirements primarily for systems with moderate load and availability requirements, if needed, it can be easily upgraded at deployment time to its unconstrained alternative GraphDB Standard. For heavy load business critical cluster deployments it can be upgraded to GraphDB Enterprise. This makes GraphDB Free an ideal choice for non-critical deployments, but also for laying the developmental foundations of smart data systems at all levels of ambition.
GraphDB™ Standard allows organizations to manage tens of billions of semantic triples on one commodity server. RDF statements can be loaded and queried at scale simultaneously.
GraphDB™ Standard performs querying and reasoning operations using file based indices. The inferencing engine also supports “Same As” functionality allowing for the identification of two or more URIs that represent the same entity even when they reside in different documents. In the table below, you can review a summary of the features supported in our Standard edition including the retraction of RDF statements. You can receive a free evaluation of GraphDB™ Standard by submitting the evaluation request form.
For additional detail on GraphDB™ Standard, refer to our documentation: GraphDB™ Standard Fact Sheet and Documentation. GraphDB™ is also available hosted on AWS and is known as GraphDB™ Cloud.
GraphDB™ Enterprise is an enterprise level triplestore proven to scale in production environments where simultaneous loading, querying and inferencing of RDF statements occur in real time. “Enterprise” has been architected to run on an enterprise replication cluster scaling to any number of master and worker nodes. Replete with failover, backup and recovery, GraphDB™ Enterprise has reliable data preservation, consistency and integrity.
This enterprise level triplestore allows you to manage extremely high volumes of RDF statements with support for inferencing and retraction of statements that are no longer valid. Please refer to the chart below which summarizes some of the more important details about Enterprise.

GraphDB DBaaS is the perfect solution for scenarios with small or medium database size and query load, where investing in software licenses and provisioning and maintaining an on-premise 24/7 server is not cost optimal.
This fully managed version of GraphDB is available as part of Ontotext Self-Service Semantic Suite (S4) along a set of services for low-cost, on-demand text analytics and metadata management on the cloud.
It provides an enterprise-grade RDF Database-as-a-Service (DBaaS), where the user does not need to deal with data base administration tasks such as installation and upgrades, provisioning and deployment, backups and restores, as well as ensuring database availability.
GraphDB™ Cloud ™ has all the features of Graph DB™ Standard with the added advantage that it has been architected to run on the Amazon Cloud as a pay-by-the-hour service. GraphDB™ Cloud can be purchased as an AMI running on a variety of Amazon EC2 server instances: from 2-core / 8 GB RAM up to 8-core / 64 GB RAM. Organizations often want to develop and test in the cloud before bringing projects in-house with an on premises installation. GraphDB™ Cloud is perfect for running limited-time projects or low-volume experiments in a production-quality setting without an investment in licenses or hardware. All GraphDB™ Cloud instances are designed to store data on user-supplied Amazon EBS volumes (network attached storage), so that your data is persisted and safe even if the instance is not running.
