Cypher

Cypher is the declarative, pattern-matching query language for property graph databases: SQL for your connected data.

Cypher is the most widely adopted query language for property graphs, initially developed by Neo4j and now an open specification via the openCypher project. It uses intuitive, ASCII-Art syntax—like `(n:Person)-[:KNOWS]->(m:Person)`—to visually express complex graph patterns. This declarative approach allows developers to efficiently retrieve, insert, and update data by focusing on *what* to find, not *how* to traverse, making it highly accessible for graph database operations.
