In this interview, Nicolas Rouyer from Orange Business Services shares their experience with Neo4j, a graph database software. They started using Neo4j for IT supervision use cases and found it useful for finding security issues in their information system. Nicolas attributes the choice of Neo4j to solving search problems such as shortest path, which was different from their other use cases. The team has seen surprising results from using Neo4j, including gaining insights into certain communities and refining data models. However, they would do things differently if given the chance, particularly in terms of data modeling and integrating with other software tools. The community around Neo4j is growing rapidly in Toulouse, France, and Nicolas encourages others to share their experiences and learn more about graphs.
