Traverser Frameworknode.traverse(description)
Language object bindings (Ruby, Python, PHP,...)node.genes.first.name
Gremlin (perl like)./outE[label='family']/inV/@name
Graph MatchingExample graphs,
Starting point by searching
RDF, SPARQL SNOMEDSELECT ?gene, ?family WHERE ...
Querying Neo4j? (II)
neo4j-kernelCore of neo4j
neo4j-indexIndexing component
neo4j-shellA command line like shell
neo4j-remote-graphdbJAVA API for interacting with the core and JAVA app
neo4j-backupComponent for backup
neo4j-graph-algoMore relevant graph algorithms
Neo4j components
Why graph databases?
Data miningYou can make algorithms for searching patterns and add AI
High-critical environmentsYou can apply neo4j for high load databases and optimize the queries and reduce costs on hardware use
Engineering in biochemical componentsYou can make algorithms for helping the study of protein synthesys, for example
Discrete event simulationYou can apply a pattern and behavior and assign everything to a graph database
Social graphEverything in user related tastes can be organized in a graph
Network architecture
Some examples...
Routing
Visualization - Gephi
Visualization - iGraph
Most widely deployed graph db in the worldACID, persistent, embedded/server
Robust: 24/7 production since 2003
Mature: lots of production deployments
Scalable: High Availability, Master failover
Community: ecosystem of tools, bindings, frameworks
Product: OSGi, Spatial, RDF, languages
Available under AGPLv3 and as commercial productBut the first one is free! For ALL use-cases
