Data-Centric Features

Fluree DB extends the role of your typical database to include trust, semantic context, and security.

Provide complete provenance and integrity to every piece of data in your system. Fluree combines transactions into immutable time-stamped ‘blocks’ and locks each block in via advanced asymmetric cryptography — making your data completely tamper-proof. Traceability of changes are tied to digital signatures for complete proof and visibility into data lifecycle.

Link, leverage, and connect information in a rich semantic web of data. Fluree sits atop W3C standard RDF with standardized JSON-LD and SPARQL query support. RDF (Resource Description Format) provides instant and lightweight interoperability across disparate systems. Fluree instantly makes data F.A.I.R. (Findable, Accessible, Interoperable, Reusable) for smarter information management and enterprise knowledge graphing.

The next generation of identity and access management: Fluree embeds privacy and security permission logic as meta-data alongside RDF data at the source. With Data-Centric security, we can share information with a zero risk of data leakage, opening up a world of data sharing and collaboration opportunities without the compounding API overhead.

Time as a first-class citizen: Fluree timestamps every update by extending RDF to include temporal metadata. "Time Travel” allows you to issue queries against any moment of time and instantly retrieve the data as of that instance. Ditch the "update and replace" database for complete historical data visibility.

Fluree Database

Semantic Web Standards

Leverage global schemas, enabling linked data to be connected through unique identities (IRIs) and industry ontologies.

Unlimited Cloud Scale

Architectural separation of update system from query server allows users to scale up load without affecting transactional performance.

Data-Centric Security

Define, execute, and manage data read/write security and governance policies at the data tier with Fluree SmartFunctions.

Trusted Data Provenance

Updates to datasets are cryptographically secured in an immutable ledger and tied to provable identities.

Multi-Modal Access

Allow consumers to access and use data in the query languages they know (GraphQL, JSONbased FlureeQL, SQL, & SPARQL).

JSON-LD Native Support

Coming Soon Fluree combines the ease of JSON documents with the power of linked data.

Modular Architecture

Fluree’s technology runs on a simple and lightweight java runtime for deployment across on-premises and cloud. Fluree’s modular stack can fit any architecture: because we de-couple the ledger server (state) from the graph database (query), you’ll never run out of scale.

  • Front-End Delivery (Embed & Scale)

    Embed an in-memory query server directly alongside your application code for real-time query speeds - with data security and permissions built directly in. Build powerful real-time applications with Fluree's Javascript database and frontend tools that deliver data directly at the edge. React and NodeJS libraries included. View on Github »

  • Graph Database (Query)

    Fluree is a stateless (linearly-scalable) semantic graph database. Native support for GraphQL, SPARQL, and JSON-based FlureeQL allow for rich and efficient "declarative" queries. RDF data format allows your apps to execute queries across disparate interoperable sources. View on Github »

  • Immutable Ledger (State)

    Fluree accepts and persists transactions in an immutable (append-only) ledger. The ledger records atomic RDF updates in chronological order using asymmetric (Sha 3-256) cryptography for guaranteed integrity and provenance. Optional decentralization via RAFT or PBFT consensus. View on Github »
