Versatile multi-model NoSQL DBMS with native graph, document, and full-text support
OrientDB combines graph, document, key‑value, full‑text, and geospatial models in a single engine, offering ACID transactions, SQL queries, and runnable on any platform via Java.
OrientDB is a Java‑based multi‑model database that unifies graph, document, key‑value, full‑text, and geospatial data structures. It targets developers, data engineers, and architects who need flexible data modeling without managing multiple specialized systems.
The engine offers ACID‑compliant transactions and a full SQL layer, allowing teams familiar with relational queries to interact with NoSQL data. Persistent pointers replace costly runtime joins, delivering rapid traversals across millions of records. Built‑in full‑text indexing, geospatial queries, and reactive APIs enable advanced search and real‑time analytics.
Running on any platform with a Java runtime, OrientDB requires no complex installation. Its multi‑master architecture provides high availability and horizontal scalability, while a granular security model controls users, roles, and predicate‑based access. Documentation and community channels support quick onboarding and ongoing maintenance.
When teams consider OrientDB, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Social network feed generation
Fast graph traversals combined with document profiles enable real‑time feed assembly.
Content management system
Full‑text search across documents with relational‑like queries simplifies content retrieval.
IoT geospatial analytics
Store sensor data with location indexing and reactive queries for instant spatial insights.
Fraud detection
ACID‑safe transactions across graph relationships support real‑time alerts and audit trails.
No. OrientDB is a NoSQL multi-model database, though it supports SQL for querying.
Yes. OrientDB provides ACID‑compliant transactions across its data models.
OrientDB is written in Java and offers bindings for multiple languages; Java is the primary runtime.
It uses a multi‑master architecture that allows horizontal scaling and high availability.
OrientDB does not provide an official managed cloud service; deployments are self‑hosted.
