OrientDB
OrientDB is an open-source multi-model NoSQL database management system that combines graph and document data models.
What OrientDB is
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. Data tools include a Graph Editor, Studio Query interface and command-line console, with native binary, HTTP REST/JSON and 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 mode requires at least 2 GB of heap, with 4 GB suggested. Transactions remain in client RAM, so their size depends on 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 Community distribution is free. Paid support examples include Basic support at 1000 € per month and Advanced support at 4000 € per month; Consultancy pricing is case by case. The documentation identifies v3.2.56 as the latest GA release.
