Graph Databases - INI

Graph databases are database management systems that represent relationships between data using nodes (vertices) and edges. Compared to relational databases, they excel at querying complex many-to-many relationships and deep hierarchical structures. They are widely used for social network analysis, recommendation systems, fraud detection, and knowledge graph construction. Representative products include Neo4j, ArangoDB, and Amazon Neptune.
