Neo4j

ELI5 — The Vibe Check

Neo4j stores data as a web of connections, like a conspiracy board with red strings connecting everything. Instead of tables, you have nodes and relationships. Perfect for when you need to find out that your user's friend's cousin also bought the same product.

Real Talk

Neo4j is the most popular graph database, storing data as nodes, relationships, and properties. It uses the Cypher query language and excels at traversing complex relationships with constant-time performance regardless of dataset size. Common use cases include social networks, recommendation engines, and fraud detection.
