Querying Graphs

Graph databases have their own query language, GQL, an ISO standard for graph databases.

Cypher is Neo4j's implementation of GQL. Cypher is a declarative language, meaning the database is responsible for finding the most optimal way of executing that query.

In this module you will learn about Cypher, including:

• The Cypher syntax
• Pattern matching
• How to use MATCH to read data
• How to use MERGE to write data
