Orient DB
The Document-Graph database, SQL and Native Queries, asynchronous commands, intents, and much more. OrientDB is "fast" ( storing 220,000 records per second on common hardware ). It supports :
- schema-less,
- schema-full and
- schema-mixed modes and
- includes SQL among its query languages along with a custom SQL based language which reduces the learning curve for those new to OrientDB.
