Insert data: CREATE (:Person {name: 'Alice', age: 30}) 2. Modify data: MATCH (p:Person {name: 'Alice'}) SET p.age = 35 3. Query data: MATCH (p:Person {name: 'Alice'}) RETURN p 4. Delete data: MATCH (p:Person {name: 'Alice'}) DELETE p The above is a simple example of the installation process and data operation of Neo4j.
