This document discusses using Neo4j for logistics and parcel routing applications. It describes a large logistics carrier that needed a new parcel routing system to handle up to 5 million parcels per day with real-time routing capabilities. Neo4j was able to provide the required extreme availability, performance, and scalability through its graph database approach since a logistics network can be modeled as a graph. Queries were also simplified compared to relational databases for the complex routing needs. The flexible graph data model could also better reflect real-world data variations.
