Yokogawa, a Japanese company with over 100 years of legacy assets, is leveraging Neo4j's graph database to drive digital transformation and unify disparate information. The company's products and customers work under extreme temperature and pressure conditions, requiring safety as their primary concern. With around 75% of engineers being operational technology experts, the remaining 25% are IT experts dealing with data islands that need integration into a knowledge graph. Yokogawa's key challenges include digitally transforming automation systems and unifying disparate data sources distributed across multiple databases, tech stacks, and infrastructures. To address these challenges, they built their different information models into a knowledge graph using Neo4j, enabling them to transfer knowledge in the form of graphs, templatize information, and use it across different refineries and customers. The company is now exploring Graph Databases and Tooling to support intuitive and generic tech stacks throughout the model life cycle, with plans to use Arrows and Neo4j's Data Importer for depiction and translation of information models into the graph database.
