Octetful Notes - Graphs - Graph Databases

This section covers graph databases and graph compute engines along with some other tools and libraries.

Neo4J

Neo4j is a highly scalable native graph database, purpose-built to leverage not only data but also data relationships. Using Neo4j, developers build intelligent applications that traverse today's large, interconnected datasets in real time. Powered by a native graph storage and processing engine, Neo4j delivers an intuitive, flexible and secure database for unique, actionable insights.

This section covers details of the Neo4J graph database.

Apache Tinkerpop

Apache TinkerPop™ is a graph computing framework for both graph databases (OLTP) and graph analytic systems (OLAP).

This section covers details of the Apache Tinkerpop framework.

Other Graph Databases & Frameworks

JGraphT

JGraphT is a Java library of graph theory data structures and algorithms

There's an Overview for Application Developers to help get you started with using the JGraphT library in your own applications.

BlazeGraph

Blazegraph™ DB is a ultra high-performance graph database supporting Blueprints and RDF/SPARQL APIs. It supports up to 50 Billion edges on a single machine. It is in production use for Fortune 500 customers such as EMC, Autodesk, and many others. It is supporting key Precision Medicine applications and has wide-spread usage for life science applications. It is used extensively to support Cyber anaytics in commercial and government applications. It powers the Wikimedia Foundation's Wikidata Query Service.
