Without a lot of hype and fanfare, OrientDB has become one of the most widely deployed graph databases. DB-engines.com currently ranks OrientDB #2 among graph databases (http://db-engines.com/en/ranking/graph+dbms) -- and now it's multi-modal, able to store documents as well.
We've been trying for a while now to bring Luca Garulli (https://www.linkedin.com/in/garulli), the author of OrientDB (http://orientdb.com/orientdb/), to Seattle. It's finally happening.
For those of you not yet familiar, OrientDB is an open source NoSQL (https://en.wikipedia.org/wiki/NoSQL) database management system (https://en.wikipedia.org/wiki/Database_management_system) written in Java (https://en.wikipedia.org/wiki/Java_(programming_language)). It is a multi-model database, supporting graph (https://en.wikipedia.org/wiki/Graph_database), document (https://en.wikipedia.org/wiki/Document-oriented_database), key/value (https://en.wikipedia.org/wiki/Key-value_database), and object (https://en.wikipedia.org/wiki/Object_database) models, but the relationships are managed as in graph databases with direct connections between records. It supports schema-less, schema-full and schema-mixed modes. It has a strong security profiling system based on users and roles and supports querying with Gremlin (https://en.wikipedia.org/wiki/Gremlin_(programming_language)) along with SQL (https://en.wikipedia.org/wiki/SQL) extended for graph traversal.
This is a rare opportunity. Come join us to welcome Luca to Seattle!
