InfiniteGraph. InfiniteGraph Graph database Website : http://www.objectivity.com/infinitegraph License : commercial Description InfiniteGraph, brought by Objectivity, is a distributed graph databases that can handle very large datasets. It was first released in 2010 and has a commercial license.
Neo4j. Neo4j Graph database Website : http://www.neo4j.org/ License : commercial/open-source Description Neo4j, the graph database developed by Neo Technology made it easier to work with graphs. Since the launch of the V1 in 2010, Neo4j garnered a lot of interest. Its open-source edition makes it very easy for developers to start experimenting with graph databases. Today, Neo Technology is the leading graph database with a long list of customer references. It remains focused on usability with recent releases bringing changes in the ETL process and data visualization.
OrientDB. OrientDB Graph database Website : http://www.orientechnologies.com/orientdb/ License : Apache 2.0 license Description OrientDB is an Open Source database with the features of both Document and Graph databases. OrientDB is written completely in Java and can run on any platform without configuration and installation.
Sparksee. Sparksee Graph database Website : http://www.sparsity-technologies.com/ License : commercial Description Sparksee (formerly known as DEX) is a proprietary graph database built for performance. It has a small footprint, is natively available for .Net, C++, Python and Java. Sparksee mobile is the first graph database available for iOS and Android.
Titan. Titan Graph database Website : http://thinkaurelius.github.io/titan/ License : Apache 2.0 license Description Titan, an other open-source project has been gaining a lot of attention lately. Though still in early stage, Titan is an ambitious project. It is a distributed graph database built to store and query graphs in the hundreds of billions of vertices and edges.
Faunus. Faunus Graph analysis Website : http://thinkaurelius.github.io/faunus/ License : Apache 2.0 license Description The team behind the Titan graph database has also released Faunus. Faunus is a Hadoop-based graph analytics engine for analyzing graphs represented across a multi-machine compute cluster. It is compatible with HBase, Cassandra or Hadoop.
Giraph. Giraph Graph analysis Website : http://giraph.apache.org/ License : Apache 2.0 license Description Giraph, the Apache project, is an iterative graph processing system built for high scalability. It is currently used at Facebook to power its famous Graph Search. At Facebook, Giraph can process a graph with trillions of connections between people, places, likes and interests in minutes. It is compatible with Hadoop.
GaphLab. GraphLab Graph analysis Website : http://graphlab.com/ License : Commercial/Open-source Description People interested in Machine Learning can turn to GraphLab to analyse their graph data. GraphLab was started as an open-source project by Prof. Carlos Guestrin of Carnegie Mellon University in 2009. Recently it has evolved in a data science toolbox but remains very useful for graph analytics.
GraphX. GraphX Graph analysis Website : https://spark.apache.org/graphx/ License : Apache 2.0 license Description Another popular solution for graph computing is Graphx. It is integrated to Apache Spark, an open-source data analytics cluster computing framework. GraphX has a built in library of algorithms and include ETL functionalities. It doesn’t offer the same performances as Giraph but is easier to use.
Key tendencies for graph analysis frameworks. Graph computation is part of the big data toolset. Here are a few key tendencies for the graph analysis frameworks : ● most graph databases have their own query language (ex : Cypher for Neo4j and Faunus for Titan ) ; ● GraphX and Giraph are bringing graph paradigms to HBase, Cassandra and Hadoop ; ● GraphBuilder, an Intel project can help transform tabular data into graphs ;
Cytoscape. Cytoscape Graph visualization Website : http://www.cytoscape.org/ License : GPL License Description Another graph visualization solution is Cytoscape. Mostly used by biologists at first, it has progressively evolved in a general platform for complex network analysis and visualization. It is desktop-based and is supported by a large community.
Gephi. Gephi Graph visualization Website : https://gephi.github.io/ License : CDDL, GPLv3 Description Gephi has played a key role in this process. It is an open-source graph visualization solution. It packs a powerful set of SNA algorithms and visualization options. Used by a wide community of scientists and data scientists, it is akin to a “Photoshop for graphs”.
Keylines. Keylines Graph visualization Website : http://keylines.com/ License : commercial Description KeyLines is a software library for graph visualization. Developed by Cambridge Intelligence, it is designed to help developers create interactive web applications around graphs.
Linkurious. Linkurious Graph visualization Website : http://linkurio.us License : commercial Description Graph visualization is going beyond the world of scientists. Linkurious is a commercial graph visualization solution that aims to democratize graph visualization. Its interface is designed for the interactive exploration of large graphs and comes directly with features common in traditional business intelligence applications (security, user management, etc).
Tom Sawyer Software. Tom Sawyer Software Graph visualization Website : https://www.tomsawyer.com/home/ License : commercial Description Tom Sawyer Software sells a collection of software development kits for graph visualization and analysis. Its products are used by established companies like NASA and Oracle. It is compatible with ActiveX, C++, Java, and .NET.
Key tendencies for graph visualization solutions. Graph visualization moving to the enterprise. Here are a few key tendencies for graph databases : ● traditional graph visualization solutions were targeted at developers and data scientists : Cytoscape, Gephi ; ● companies like Cambridge Intelligence and Linkurious are making graphs easier to understand for business people, not just data scientists ; ● a few projects try to integrate the different layers of the graph technologies into complete products : Dendrite, Linkurious, Tom Sawyer Software ;
