OrientDB is an open source document-graph database with the support of ACID Transactions, SQL and native queries, asynchronous commands, intents, and much more.

OrientDB can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. Traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages.

OrientDB adheres to the NoSQL movement even if supports a subset of SQL as query language. In this way it is easy to start using it without to learn too much new stuff.
