Cypher and Neo4j
The Neo4j graph database is all about relationships. It allows to model domains of connected data easily. Querying using a imperative API is cumbersome and bloated. So the Neo Technology team decided to develop a query language more suited to query graph data.
Taking inspiration from SQL, SparQL and others and using Scala to implement it turned out to be a good decision. The parser-combinator library, functional composition and lazy evaluation helped us to easily go ahead. Join us to learn the journey of its inception to a being usable tool.
