Project Summary
OrientDB is a deeply scalable Document-Graph DBMS with the flexibility of the Document databases and the power to manage links of the Graph databases. It can work in schema-less mode, schema-full or a mix of both. Supports advanced features such as ACID Transactions, Fast Indexes, Native and SQL queries. It imports and exports documents in JSON. Graphs of hundreads of linked documents can be retrieved all in memory in few milliseconds without executing costly JOIN such as the Relational DBMSs do.
