Top 25 Graph Databases
Top 25 Graph Databases : A graph database is based on graph theory, uses nodes, properties, and edges and provides index-free adjacency. These database uses graph structures with nodes, edges, and properties to represent and store data. Every element contains a direct pointer to its adjacent elements and no index lookups are necessary in a graph database. Neo4j, AllegroGraph, Oracle Spatial and Graph, Teradata Aster, ArangoDB, Graphbase, InfiniteGraph, Bitsy, Horton, HyperGraphDB, DEX/Sparksee, Titan. VelocityGraph, VertexDB, InfoGrid, Oracle NoSQL Database, OrientDB, Blazegraph, Cayley, Weaver, Stardog, Sqrrl Enterprise, GraphDB, MapGraph and IBM System G Native Store are some of the top graph databases in no particular order.

Neo4j is an open-source graph database, implemented in Java. This is an embedded, disk-based, fully transactional Java persistence engine that stores data structured in graphs rather than in tables.Neo4j speeds write throughput significantly across the board, as much as 100 times in certain cases to benefit highly concurrent applications while leveraging available hardware much more efficiently. This is achieved through faster buffering of updates, and a new unified transaction log that now serves both the graph and its indexes.
AllegroGraph is a modern, high-performance, persistent graph database. AllegroGraph uses efficient memory utilization in combination with disk-based storage, enabling it to scale to billions of quads while maintaining superior performance. AllegroGraph supports SPARQL, RDFS++, and Prolog reasoning from numerous client applications. AllegroGraph is designed to store RDF triples, a standard format for Linked Data. A custom browser, Gruff, is available for viewing the graph.
3.Oracle Spatial and Graph

The graphical interface includes summary dashboards, graphical views of query and process execution.
Graphbase is a customizable, distributed, small-footprint graph store with a rich tool set. GraphBase makes massive, highly-structured data stores possible because it was built from scratch to manage large graphs. GraphBase features include tiny memory and storage footprint, distributable – out of the box, built-in support for traversal heuristics and graph-based transactions.
InfiniteGraph is a distributed and cloud-enabled commercial product with flexible licensing.InfiniteGraph enables organizations to achieve greater return on their data related investment by helping them “connect the dots” on a global scale, ask deeper and more complex questions, across new or existing data stores.
Bitsy is a small, fast, embeddable, durable in-memory graph database that implements the Blueprints API. Features include support for most Blueprints features including key indices and threaded transactions, ACID guarantees on transactions, designed for multi-threaded OLTP applications, implements optimistic concurrency control, data stored in readable text files and serialization using the Jackson JSON processor.
Horton is a research project in the eXtreme Computing Group to enable querying large distributed graphs. It consists of a graph library built on top on Orleans that targets hosting large graphs in a data center. The library provides a querying interface to search the graph for matching paths.
HyperGraphDB is an open source data storage mechanism based on directed hypergraphs. This can be used as an embedded object-oriented database for Java projects of all sizes or a graph database or a (non-SQL) relational database. Features include powerful data modeling and knowledge representation, graph-oriented storage, N-ary, higher order relationships (edges) between graph nodes, graph traversals and relational-style queries, customizable indexing and extensible, dynamic DB schema through custom typing.
DEX/Sparksee is a high performance and scalable graph database management system . The main characteristics is its query performance for the retrieval & exploration of large networks. Sparksee 5 mobile is the first graph database for mobile devices. Sparksee makes space and performance compatible with a small footprint and a fast analysis of large networks. SparkseeIt is natively available for .Net, C++, Python, Objective-C and Java, and covers the whole spectrum of Operating Systems.
Titan is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster. Features include elastic and linear scalability for a growing data and user base, data distribution and replication for performance and fault tolerance, multi-datacenter high availability and hot backups and support for ACID and eventual consistency.
VelocityGraph is an open source C# .NET hybrid NoSQL Graph Database and Object Database that can be Embedded/Distributed. Features include scalable smart caching enables millions of database to be used without running out of memory. High Performance objects are created the same way transient objects are and are made persistent efficiently when requested, persistence does not change the object, just adds an object identifier.
VertexDB is a high performance graph database server that supports automatic garbage collection.Vertex is built on libevent and tokyocabinet. It uses HTTP as it’s communication protocol and JSON as it’s response data format. It’s BSD licensed and was written by Steve Dekorte and Rich Collins.
InfoGrid is a Web Graph Database with a many additional software components that make the development of REST-ful web applications on a graph foundation easy. InfoGrid is open source, and is being developed in Java as a set of projects. InfoGrid provides valuable higher-level services than JEE Application Servers do themselves. Applications have a choice in the persistence layer, they can write to relational databases, just like in a RDBMS-centric architecture, but can also write to grid technology, or other NoSQL Stores. InfoGrid provides a common abstraction layer.
16. Oracle NoSQL Database
RDF Graph for Oracle NoSQL Database is a feature of Enterprise Edition providing W3C RDF graph capabilities in NoSQL Database.The Oracle NoSQL Database is a distributed key-value database. It is designed to provide highly reliable, scalable and available data storage across a configurable set of systems that function as storage nodes. Data is stored as key-value pairs, which are written to particular storage node(s), based on the hashed value of the primary key
OrientDB is a 2nd Generation Distributed Graph Database with the flexibility of Documents in one product with an Open Source commercial friendly license. OrientDB is fast and can store 220,000 records per second on common hardware.OrientDB supports schema-less, schema-full and schema-mixed modes and has a strong security profiling system based on user and roles and supports SQL amongst the query languages.
Blazegraph is specifically designed to support big graphs offering both Semantic Web (RDF/SPARQL) and Graph Database (tinkerpop, blueprints, vertex-centric) APIs. It features robust, scalable, fault-tolerant, enterprise-class storage and query and high-availability with online backup, failover and self-healing.
