How I Passed the Neo4j Certified Professional Exam and Built a Simple Graph

I recently earned the Neo4j Certified Professional credential, and I want to share a quick demo that highlights what I learned while preparing for the exam.

Modeling a Simple Social Graph

Graphs are about nodes and relationships. I created a small example to show how Neo4j makes this powerful.

Create sample data

cypher
CREATE (a:Person {name:'Alice'}),
       (b:Person {name:'Bob'}),
       (c:Person {name:'Carol'}),
       (i:Interest {name:'Graph Databases'}),
       (a)-[:FRIEND_WITH]->(b),
       (b)-[:FRIEND_WITH]->(c),
       (a)-[:INTERESTED_IN]->(i);
