Writing Data to Neo4j

In this module you will learn how to update the graph using CypheriFull definition for Cypher (opens in a new tab)Neo4j's implementation of GQL, the ISO standard query language for graph databases. It is declarative: you describe the pattern to find, and the database decides how to find it. and the Movies example dataset.

You will learn to:

• Use MERGE to create nodesiFull definition for node (opens in a new tab)A vertex in a graph. In a property graph it can carry labels and properties. in the graph.
• Use MERGE to create relationshipsiFull definition for relationship (opens in a new tab)A named, directed connection between two nodes. Every relationship has a type, a start node and an end node. in the graph.
• Create, update and remove propertiesiFull definition for property (opens in a new tab)A named value stored on a node or a relationship. 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.

Again, here is the domain model and how it is represented in our graph:
