OrientDB is a multi-model NoSQL document database that provides both graph and document structures and queries. It supports ACID transactions, schema-full and schema-less modes, HTTP/binary protocols, and allows both SQL-like and native graph queries. OrientDB provides APIs for Java, JRuby and other languages to interface with the database.
