Writing Data to Neo4j

In this module you will learn how to update the graph using Cypher and the Movies example dataset.

You will learn to:

  • Use MERGE to create nodes in the graph.

  • Use MERGE to create relationships in the graph.

  • Create, update and remove properties for nodes and relationships in the graph.

  • Perform conditional MERGE processing, depending on what is in the graph.

  • Delete nodes and relationships from the graph.
