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 node element types, add relationship types and constraints, 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 properties 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
