OrientDB is the Second Generation Distributed Graph Database with the flexibility of Documents in one product with a dual licensing model. Legacy Graph Databases lack the features that Big Data demands: multi-master replication, sharding and more flexibility for modern complex use cases.
OrientDB is incredibly fast: it can process more than 200,000 records per second on commodity hardware. When using the document model, the relationships are managed in a graph fashion with direct connections among records. You can traverse trees and graphs of billion records in a few milliseconds. This gives you the flexibility and connectedness needed by modern apps.
Furthermore, OrientDB supports schema-less, schema-full and schema-mixed modes. Has a strong security profiling system based on user and roles. Supports SQL amongst the query languages making the migration straightforward for those skilled in the relational database world.
OrientDB puts the best features of relational, document and graph databases in an elegantly engineered product. Orient Technologies is the main sponsor and the commercial supporter of OrientDB, offering subscriptions, support, training, and consulting for the database.
