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.
Key Features
- 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.
