  Gremlin ● Provides control over the traversal algorithm ● Pipe & Filter – similar to jQuery ● Works across different graph databases ● Based on Groovy (limited to Java)
• 9.
  Gremlin g.v(1) .in('COMPANION_OF') .out('APPEARED_IN') .has('title', "The Doctor's Daughter") .back(2)
• 10.
  Gremlin ● Can modify the graph ● Allows to run arbitrary code ● Implementation not as stable in Neo4j

  Cypher START doctor =node(1) MATCH doctor <-[:COMPANION_OF]- companion, companion -[:APPEARED_IN]-> episode WHERE episode.title = "The Doctor's Daughter" RETURN companion, companion.character

  hirevoice/neo4jphp-ogm Pros: Cons: ● Fast (bulk operations) ● Supported by me ● Feels like Doctrine ● Skim ● Benefits from type documentation checking ● Implementation still ● Well tested partial ● Bundles and modules available (many)
