Learn to create and apply labels on nodes in Neo4j Cypher using the create clause, colon-prefixed labels like :Course, and single-query patterns to link courses, categories, and creators.

Learn to create and query nodes with multiple labels in Neo4j Cypher, creating two labels (database and graph database), retrieving labels with labels(), and assigning labels with set.

Learn the four constraint types in Neo4j: uniqueness, attribute existence, relationship existence, and node key—and how constraints create an index and handle composite constraints on username and email.

Learn how to implement the node key constraint in Neo4j, enforcing unique and existing combinations of username and email on user nodes, with attention to attribute order.
