Graph databases are being used by companies to solve tough problems, and one of the key use cases is master data management. Master data is highly connected and shared, and poorly built systems can cost business agility. Graph technology allows for modeling, storing, and querying hierarchies, metadata, and connections in master data, making it easier to manage and providing a consistent vision of enterprise data. The use of graph databases has been demonstrated in the case study of Airbnb, where they used Neo4j to tie together their entire data ecosystem, make it searchable, relevant, and trustworthy, and empower employees to find resources with confidence. By using graph technology for master data management, companies can gain real-time insights and make better business decisions.
