Neo4j
Specific characteristics

Neo4j is a native graph database that is built to store, query and manage highly connected data more efficiently than other databases. Data relationships are first class citizens and can be traversed in constant time without index lookups. That allows even complex queries to deliver results in milliseconds than in minutes. Architected for the property graph model, it provides optimized mechanisms to work with todays complex domains and use-cases.

Competitive advantages

Neo4j is the only transactional database that combines everything you need for performance and trustability in applications that bring data relationships to the fore: native graph storage, native graph processing, graph scalability, high availability, built-in ETL, and integration support, plus Cypher, a powerful and expressive language for queries using vastly less code than SQL.

Typical application scenarios
  • Real-Time Recommendations
  • Master Data Management
  • Identity and Access Management
  • Network and IT Operations
  • Fraud Detection
  • Graph-Based Search
Key customers

eBay, Walmart, Cisco, UBS, HP, CenturyLink, Telenor, TomTom, Telenor, The National Geographic Society
