OrientDB

Creators and supporters of OrientDB, the leading multi-model database with a graph engine

OrientDB (ex Orient Technologies) is the company that built OrientDB, the High-Performance Transactional Graph Database. OrientDB breaks the NoSQL trend about BASE consistency by offering a full ACID Transactional DBMS. The Graph Database capabilities together with the flexible Schema-Less model allow to build complex domains. OrientDB scales on multiple servers with ZERO configuration, just start a new server and it will get the workload of the existent cluster.
