Graph Database

Explore, manage, store, and analyze graph data in Neo4j^®使用MATLAB的数据库^®interface to Neo4j orNEO4J螺栓协议的数据库工具箱™接口

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^®使用Cypher查询语言查询。

您也可以使用Bolt协议连接到Neo4J数据库。您可以使用相同的功能与存储在Neo4J数据库中的图形数据进行交互。要使用螺栓协议连接，您必须安装Database Toolbox Interface for Neo4j Bolt Protocol.
