What makes a good DB?
Separate Logic and DataSupport Ad-Hoc queriesBe persistentScale good enough
The property graph modelCore abstractions:
NodesRelationships between nodesProperties on both
Traversal frameworkHigh performancequeries on connecteddata sets
Other bindingsLangs, REST, Gremlin, RDF

“Just 3 years ago, the data sets our product handled were very simple. But the past 9-12 months have seen an e x p l os i on of the number of relationships between things.”
A web where the default is social → an explosion of graph-y data
Why graph databases?
How ego are you? (aka other impls?)Franz’ Al l e groGrap h (http://agraph.franz.com)
Proprietary, Lisp, RDF-oriented but real graphdb
Sones grap h DB (http://sones.com)
Proprietary, .NET, in beta
Twitter's Fl oc k DB (http://github.com/twitter/flockdb)
Twitter's (graph) database for large and shallow graphs
Google P re g e l (http://bit.ly/dP9IP)
We are oh-so-secret
Objectivity's I nfi n i te Grap h (http://infinitegraph.com)
New, closed OODB with Graph Layer on top
Most widely deployed graph db in the worldRobust: 24/7 production since 2003Mature: lots of production deploymentsCommunity: ecosystem of tools, bindings, frameworks
Available NOW under AGPLv3 / commercial licenseAGPLv3: “if you’re open source, we’re open source”If you have proprietary software? Must buy a commercial licenseBut the fi rst one is free! For ALL use-cases.
