Graph types

Cypher 25 onlyEnterprise EditionIntroduced in Neo4j 2026.02

Graph types allow you to specify a graph schema for a database.

When a database is created, it has an empty graph type, meaning it is free from any constraints on what can be stored in a database. Setting a graph type, typically done following the creation of a database, enables users to impose a schema on the nodes, relationships, and properties included in the graph type, thereby ensuring the integrity and quality of the data in a graph.

Cypher® supports open graph types, meaning that a graph type only constrains the data included by the graph type. It does not impose any constraints on nodes, relationships, and properties not included by the graph type.
