Cypher was originally intended to be used with the graph database Neo4j, but was opened up through the openCypher project in October 2015. [ 3 ] The language was designed with the power and capability of SQL (standard query language for the relational database model ) in mind, but Cypher was based on the components and needs of a database built ...
OrientDB is the 6th most popular graph database according to the DB-Engines graph database ranking, [3] as of January 2024. The development of OrientDB relies on an open-source community. The project uses GitHub [ 4 ] to manage the sources, contributors and versioning.
JanusGraph supports global graph data analytics, reporting, and ETL through integration with big data platforms (Apache Spark, Apache Giraph, Apache Hadoop). [ 7 ] JanusGraph supports geo, numeric range, and full-text search via external index storages ( ElasticSearch , Apache Solr , Apache Lucene ).
Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs (as in nodes and edges, not as in bar charts) specified in DOT language scripts having the file name extension "gv". It also provides libraries for software applications to use the tools.
Graph databases are commonly referred to as a NoSQL database. Graph databases are similar to 1970s network model databases in that both represent general graphs, but network-model databases operate at a lower level of abstraction [3] and lack easy traversal over a chain of edges. [4] The underlying storage mechanism of graph databases can vary.
