Neo4j database node


After creating a Neo4j® database connection using the MATLAB® interface to Neo4j, explore nodes in the database. With a Neo4jNode object, you can explore the node degree and relationship types of the nodes in the database.


Create a Neo4jNode object using searchNodeByID or searchNode.


expand all

Node identifier for the unique node in the Neo4j database, specified as a double.

Data Types: double

Node data consisting of property keys and values for the unique node in the Neo4j database, specified as a structure.

Data Types: struct

Node labels of the unique Neo4j database node, specified as a character vector for one label or as a cell array of character vectors for multiple labels.

Data Types: char | cell

Object Functions

nodeDegreeIn- and out-degree for each associated relationship type for Neo4j database node
nodeRelationTypesAssociated relationship types for Neo4j database node

Create a Neo4j® database connection using the URL http://localhost:7474/db/data, user name neo4j, and password matlab.

url = 'http://localhost:7474/db/data';
username = 'neo4j';
password = 'matlab';

neo4jconn = neo4j(url,username,password);

Check the Message property of the Neo4j® connection object neo4jconn.

ans =


The blank Message property indicates a successful connection.

Search the database for the node with node identifier 2 using the Neo4j® database connection neo4jconn.

nodeid = 2;

nodeinfo = searchNodeByID(neo4jconn,nodeid)
nodeinfo = 

  Neo4jNode with properties:

        NodeID: 2
      NodeData: [1×1 struct]
    NodeLabels: 'Person'

nodeinfo is a Neo4jNode object that contains these properties:

  • Node identifier

  • Node data

  • Node labels

Access the property keys and values of the node using the property NodeData.

ans = 

  struct with fields:

    name: 'User2'
