Graph databases are used when relationships between entities are as important as the entities themselves — supply chain networks, social graphs, and dependency trees are natural fits. Engineers build ETL pipelines that extract relational data and load it into Neo4j as a graph for relationship-based analytics.
Python data engineers use `pyorient` to connect to OrientDB and run graph queries alongside document operations. A common use case is building knowledge graph pipelines — ingesting entity documents and their relationships, querying multi-hop connections to discover related entities, and exporting subgraphs for ML feature engineering.
