Neo4j graphs in the real world - graph days d.c. - april 14, 2015
This document discusses several real-world use cases for graph databases across different industries: 1) It describes how graph databases have been used for master data management by companies like die Bayerische insurance and Classmates social network to create a unified view of customer and organizational data. 2) Graphs have also been applied to network and IT operations management by the Royal Netherlands Meteorological Institute to optimize infrastructure and by Telenor for identity and access management. 3) Fraud detection in industries like banking, insurance, and ecommerce is another common use case, with graphs helping to connect discrete user accounts and transactions to detect rings of fraudulent activity.

Editor's Notes
- #7 Field sales unit needed easy access to policies and customer data in variety of ways Growing business needed growing support Existing IBM DB2 system unable to meet performance requirements as it scaled Needed 24/7 system for sales unit outside the company
- #10 Scale: Neo4j can handle 34B nodes and 34B relationships
- #19 Fraudsters have gotten smart in order to pull off large scam or theft, they coordinate multiple bits of activity within shaded area.
- #22 Ten people collude to commit insurance fraud, five false accidents are staged Assuming an average claim of $40K per injured person and $5K per car, the ring can claim up to $1.6M for 40 people injured! where each person plays the role of the driver once, a witness once and a passenger three times.
- #23 Need to include all approaches to catch rookies and experienced fraudsters
- #25 Can do one or both but able to do more: jump up category trees, etc.
- #30 Slowest query on MySQL took longer than their fastest delivery
- #32 Discharge nurses and intake coordinators: Met fast, real-time performance demands Supported queries span multiple hierarchies including provider and employee-permissions graphs Improved data model to handle adding more dimensions to the data such as insurance networks, service areas and care organizations Greatly simplified queries, simplifying multi-page SQL statements into one Neo4j function Improve poor performance of Oracle solution Support more complexity including granular, role-based access control Different roles use the tool and different roles able to see different things Need a smart search – not just searching for a keyword – data model according to natural structure and then exposing for search gives you enormous power when searching
