TL;DR

OrientDB is a multi-model database with graph and document capabilities. It replaces single-model proprietary databases for teams that need relationship traversal and document storage in one self-hosted database. Apache-2.0 licensed.Apache-2.0 · Java · 5K stars · Active this month

who it's for

Who OrientDB is for#

Application teams with connected records

Use OrientDB when documents and relationships are both central to the application data model.

Skip if:

Your workload is straightforward relational data or analytics better served by PostgreSQL or a warehouse.

Teams evaluating graph databases

Use OrientDB when self-hosted graph traversal matters and document-style records are also needed.

Skip if:

You want the largest graph database ecosystem and managed service around Neo4j.

the problem

The problem it solves#

Some applications need both document-style records and graph-style relationships. Splitting that data across separate databases can create synchronization work, query complexity, and unclear ownership over shared entities.

Teams evaluating graph databases also face cost and lock-in concerns. If relationship queries are core to the product, the database model should not be trapped behind a vendor-only managed service.

how OrientDB solves it

How it solves it#

Graph and document data model

OrientDB supports both graph and document-style data, allowing teams to represent connected entities and rich records in one database model.

Self-hosted database deployment

Teams can run OrientDB themselves rather than relying only on a managed proprietary graph database.

SQL-like query approach

OrientDB uses a query style designed to feel familiar to database users while supporting graph-oriented relationships.

strengths · trade-offs

Strengths and trade-offs#

Strengths

  • Useful for connected document dataOrientDB fits applications where records have rich attributes and relationships matter, such as catalogs, identity maps, or networked domain models.
  • Avoids running two databases for some workloadsA multi-model approach can reduce the need to synchronize separate document and graph stores when one database can cover both needs.

Trade-offs

  • -Multi-model fit must be provenA multi-model database is not automatically better. Teams should benchmark their actual query patterns before replacing a specialized graph or document database.

FAQ#

What is OrientDB?

OrientDB is a multi-model database that supports graph and document data models.

Is OrientDB a Neo4j alternative?

OrientDB can replace Neo4j for some graph workloads, especially when document data is also important. Neo4j has a larger graph-specific ecosystem.

Can OrientDB be self-hosted?

Yes. OrientDB is a database project that teams can run on their own infrastructure.
