Cypher Query Language
Example HR Query in SQL
The Same Query using Cypher
MATCH (boss)-[:MANAGES*0..3]->(sub),
(sub)-[:MANAGES*1..3]->(report)
WHERE boss.name = “John Doe”
RETURN sub.name AS Subordinate,
count(report) AS Total
Project ImpactLess time writing queries
• More time understanding the answers
• Leaving time to ask the next question
Less time debugging queries:
• More time writing the next piece of code
• Improved quality of overall code base
Code that’s easier to read:
• Faster ramp-up for new project members
• Improved maintainability & troubleshooting

8. Graph Transactions Over

29. Performance & High Availability:
Neo4j Causal Clustering
• Architected to guarantee graph consistency
Inside instances and across the cluster
• No single points of failure
• Seamless integration with Drivers, Bolt
Protocol and Cluster
No external load balancer required
• Optimized for maximum query throughput
and response time
• Choice of application guarantees
“Read your own writes” vs. “Read any”
ENTERPRISE HIGH AVAILABILITY & SCALABILITY FEATURES

30. Neo4j Causal Clustering
Multi-Data Center Capability*
Causal Clusters can now span data centers
• Clusters can be subdivided into groups and spread across
DCs
• Read-time choice of consistency at global scale:
“Read Any”, “Read-your-own-Writes”
Tiered Subclusters boost performance
• Speeds local reads and writes
• Replica servers pull from nearest
replicas minimizing WAN traffic
Topology-aware stack insulates developers & apps from
the many complexities of clustering
Improved Cloud Delivery via RPM, Azure and AWS EC2

31. Productivity & Governance:
Schema Constraints
• Database-enforced schema
• Node Keys: enforce data uniqueness across a specified set of properties
• Property Existence Constraints: ensure that specified properties always exist for
given nodes & relationships
• Improves developer productivity & data quality
• Avoids need to encode data rules into the application
• Helps ensure data consistency within large teams
• Eases data integration across other enterprise systems

35. Background
• SF-based C2C rental platform
• Dataportal democratizes data access for
growing number of employees while improving
discoverability and trust
• Data strewn everywhere—in silos, in segmented
departments, nothing was universally accessible

• Offers search with context & metadata, user &
team-centric pages for origin & lineage
• Nodes are resources: data tables, dashboards,
reports, users, teams, business outcomes, etc.
• Relationships reflect consumption, production,
association, etc.
• Neo4j, Elasticsearch, Python

effective competitive differentiator for
organizations pursuing data-driven operations
and decisions after the design of data capture.”
“In a recent Forrester survey, 51% of global data
and analytics technology decision makers either
are implementing, have already implemented, or
are upgrading their graph databases."
“We expect the graph database market to grow
significantly as organizations look to new
approaches in dealing with silos of data.”
Source: Vendor Landscape: Graph Databases, October 6, 2017
“By the end of 2018, 70% of leading organizations
will have one or more pilot or proof-of-concept
efforts underway utilizing graph databases.”
