Database Toolbox enables you to connect to a Neo4j graph database using the MATLAB interface to Neo4j. After creating a Neo4j connection, you can search the graph database data. Create, update, and delete nodes and relationships in the database. Update node labels and properties and update relationship properties. Perform analysis with graph network algorithms using the MATLAB directed graph. Store the directed graph in the Neo4j database. Traverse and analyze graph data by executing Cypher® queries using the Cypher query language.
You can also connect to a Neo4j database using the Bolt protocol. You can use the same functionality to interact with graph data stored in a Neo4j database. To connect using the Bolt protocol, you must install the Database Toolbox Interface for Neo4j Bolt Protocol.
