Introduction to the
graph
technologies
landscape.

2. Introduction.
“At Linkurious we believe graph technologies can
have a powerful impact in the way we think about
data and turn it into new products. This small
report is meant to give you a glimpse into the
emerging graph ecosystem. May it inspire you to
join, use or launch graph projects.”

Neo4j.
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.

13. 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.

14. 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.

15. 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.

16. A growing need to store
large graphs.
Key tendencies for graph databases.
Here are a few key tendencies for graph databases :
● graph databases are still a small niche within the NoSQL space but they are coming into
their own ;
● choose the right graph database for your particular use case ;
● other big data solutions are sometimes used to store large graphs : Accumulo, HBase ;
● there exist a few integrated products that mix storage capabilities and advanced
functionalities : Sqrrl, YarcData ;

Second layer : the graph analysis frameworks.

18. 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.

19. 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.

20. 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.

21. 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.

22. 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 ;

24. 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.

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”.

26. 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.

29. 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 ;
