OrientDB is an open-source multi-model NoSQL database management system that combines graph and document data models. It supports SQL and Gremlin queries, ACID transactions, and graph algorithms. Users can work through a Graph Editor, Studio Query interface, or command-line console, and connect through native binary, HTTP REST/JSON, or Java-wrapped drivers. Listed clients and integrations include Java, JDBC, Spring Data, Node.js, PHP,.NET, Python, Go, Ruby, and Scala. OrientDB documents a multi-master distributed architecture in which each server can read and write; distributed operation requires at least 2 GB of heap, with 4 GB suggested. Transactions stay in client RAM, so their size is limited by available JVM heap. Security options include TLS 1.2 in-transit encryption and AES or DES at-rest database encryption, neither enabled by default. The documentation identifies v3.2.56 as the latest GA release. The Community distribution is free; paid support examples start at 1000 € per month.
