What is Cypher?
Cypher is an open graph query language that Neo4j uses. If you're familiar with SQL, you'll find Cypher to be similar. Neo Technologies has good resources on learning Cypher.
Enterprise vs Community Edition
By default our graph instances run Neo4j Enterprise Edition. The other edition is Community, which older customers may be running.
Both editions feature:
Property Graph Model
Native Graph Processing & Storage
Cypher – Graph Query Language
High-Performance Native API ("Bolt")
Enterprise Edition adds:
Clustered Replication (High-availability cluster support)
Hot Backups (Graph Story automatically backs-up Enterprise instances daily, weekly, and monthly)
Enterprise Lock Manager
Cypher Query Tracing
Property Existence Constraints
Enterprise Edition is not open source, and requires a license. Graph Story is a Neo4j Solution Partner, and licenses are included in the Graph Story subscription cost. License cost varies based on the size of the company.
