| Description | A property graph database that stores data as fixed-size records in linked lists for index-free adjacency traversal. Offers community and commercial editions with an extensive graph algorithms library. | A PostgreSQL extension that exposes graph algorithms as plain SQL functions. Each function takes arrays of source and target node ids and returns a table, covering PageRank, betweenness, closeness and eigenvector centrality, strongly and weakly connected components, Louvain community detection, Dijkstra, topological sort and cycle detection. |
