OrientDB is an open source NoSQL database management system written in Java.
It has a strong security profiling system based on users and roles and supports querying with Gremlin along with SQL extended for graph traversal.
While OrientDB includes a SQL layer, the support for edges effectively means that these may be used to traverse relationships rather than employing a JOIN statement.
Since 2012, the project is being sponsored by OrientDB LTD (former Orient Technologies LTD), a for-profit company with Luca as its CEO and founder.
[14][15] The first time the word "multi-model" has been associated to the databases was on May 30, 2012, in Cologne, Germany, during Luca Garulli's keynote "NoSQL Adoption – What’s the Next Step?".
On September 1, 2021,[21] the original founder Luca Garulli left SAP (company) and created a new database project ArcadeDB with a similar data presentation model after SAP decided to stop providing commercial support for OrientDB.
