From the webpage:
Key principles and capabilities of Cypher are as follows:
- Cypher matches patterns of nodes and relationship in the graph, to extract information or modify the data.
- Cypher has the concept of identifiers which denote named, bound elements and parameters.
- Cypher can create, update, and remove nodes, relationships, labels, and properties.
- Cypher manages indexes and constraints.
You can try Cypher snippets live in the Neo4j Console at console.neo4j.org or read the full Cypher documentation at docs.neo4j.org. For live graph models using Cypher check out GraphGist.
If you plan on entering the Neo4j GraphGist December Challenge, you are probably going to need this Refcard.
I first saw this in a tweet by Peter Neubauer.
