Neo4j for Beginners – Graph DB Simplified

Neo4j is a graph database system that stores data as nodes and relationships instead of rows and columns.

🧠 When to Use It?

• Social networks – friend of a friend
• Fraud detection – linked accounts
• Recommendation engines – user-item paths

💡 Benefits

1. Query depth relationships easily
2. No joins needed – better performance
3. Visual and intuitive

Try Cypher queries like:

MATCH (a)-[r]->(b) RETURN a.name, r.type, b.name

Insight: Graph DBs like Neo4j model complex real-world systems far better than SQL.
