APIs and Drivers

OrientDB supports 3 kinds of drivers:

Native binary remote, that talks directly against the TCP/IP socket using the binary protocol
HTTP REST/JSON, that talks directly against the TCP/IP socket using the HTTP protocol
Java wrapped, as a layer that links in some way the native Java driver. This is pretty easy for languages that run into the JVM like Scala, Groovy and JRuby

Look also at the available integration with Plugins and Frameworks.

This is the list of the known drivers to use OrientDB through different languages:

Name	Type	Description
Java (native) API	Native	Native implementation.

Any Java driver	Native	Scala runs on top of JVM and it's fully compatible with Java applications like OrientDB
Scala Page	Native	Offers suggestions and examples to use it without pains
Scala utilities and tests	Native	To help Scala developers using OrientDB
R driver	HTTP	R Bridge to execute queries against OrientDB Server
MarcoPolo Elixir driver	Binary	This driver allows Elixir application to interact with OrientDB. Elixir language leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.
