Schema Enforcement with Graph Types

In this module, you will learn how to define and manage a graph type schema for the recommendations dataset.

You will start with nodeiFull definition for node (opens in a new tab)A vertex in a graph. In a property graph it can carry labels and properties. element types, add relationshipiFull 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. types and constraintsiFull definition for constraint (opens in a new tab)A rule the database enforces on every node or relationship with a given label or type, rejecting any write that breaks it., and finish by assembling a complete enforceable schema for the entire graph.

By the end of this module, you will be able to:

• Define node element types with typed propertiesiFull definition for property (opens in a new tab)A named value stored on a node or a relationship. and constraints
• Add relationship element types that enforce how nodes connect
• Use SET, ADD, ALTER, and DROP to manage your graph type over time
• Build a complete, enforceable schema for a real-world dataset
