OrientDB
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.
Features include:
- Designed to be extremely fast
- Extremely light on system resources with no dependencies
and no libraries needed
- Supports ACID transactions. On crash it recovers
the pending documents
- Native management of graphs. 100%
compliant with TinkerPop
Blueprints standard for GraphDBs
- Supports SQL language with extensions
to handle relationships without JOINs, manage trees and graphs of
connected documents
- Supports natively HTTP, RESTful
protocol and JSON without use 3rd party libraries
and components
- Local mode: Direct access to the database bypassing the
Server. Perfect for scenarios where the database is embedded
- SQL: supports SQL language with extensions to handle
relationships without SQL join, manage trees and
graphs of connected documents
- Web ready: supports natively HTTP, RESTful
protocol and JSON without use 3rd party libraries and components
- Supported
types: String, byte, short, integer, long, float, double, boolean,
date, datetime, binary, link, link list, link set, link map, embedded,
embedded list, embedded set, and embedded map
- Native support for the inheritance classes taken by the
Object Orientation paradigm
- Drivers to use OrientDB through different languages: Java,
Javascript, PHP, Python, .NET, Ruby, Scala, C Language binding
- Easy JAVA APIs
- Embeddable
- Runs on any platform
