What is OrientDB? Copy Chapter

OrientDB is an Open Source Multi-Model NoSQL DBMS with the support of Native Graphs, Documents,
Full-Text search, Reactivity, Geo-Spatial and Object Oriented concepts. It's written in Java and it's amazingly fast.
No expensive run-time JOINs, connections are managed as persistent pointers between records.
You can traverse thousands of records in no time. Supports schema-less, schema-full and schema-mixed modes.
Has a strong security profiling system based on user, roles and predicate security and supports SQL amongst the query languages.
Thanks to the SQL layer it's straightforward to use for people skilled in the Relational world.

Is OrientDB a Relational DBMS? Copy Chapter

No. OrientDB adheres to the NoSQL movement even though it supports ACID Transactions and
SQL as query language. In this way it's easy to start using it without having to learn too much new stuff.

Easy to install and use Copy Chapter

Yes. OrientDB is totally written in Java and can run on any platform without configuration and installation.
Do you develop with a language different than Java? No problem, look at the Programming Language Binding.
