Nodes represent entities in your data model (like Person, Product, Company). They can have:

• Labels to categorize them (e.g., :Person, :Movie)
• Properties as key-value pairs
  Relationships connect nodes and represent how entities are related. They:
• Always have a direction (though can be traversed both ways)
• Must have exactly one type (e.g., :ACTED_IN, :FRIENDS_WITH)
• Can have properties
  Properties are key-value pairs that store data on both nodes and relationships.
  Example:

(person:Person {name: "Tom Hanks", born: 1956})
-[:ACTED_IN {role: "Forrest"}]->
(movie:Movie {title: "Forrest Gump", released: 1994})
