Postgres as Graph Database Using pgRouting: pgRouting, a Postgres extension for geospatial routing, enables basic graph functionalities and can be combined with PostGIS. It can model graphs for various applications beyond GIS, like task scheduling (using directed acyclic graphs for dependencies) and resource allocation in distributed systems (optimizing paths for data). It also supports recommendation engines utilizing knowledge graphs to analyze connections between entities (like YouTube videos or users). The algorithms implemented in pgRouting, such as Dijkstra’s and A*, help find optimal paths in these networks, showcasing versatile applications of Postgres as a graph database.
