Hello,
I’m using in a project Postgresql and PostGIS for a geospatial data model, but now I need also a graph in this
structure,so my question is, is there any existing
extension for Postgres to build a graph. I found ltree but this is for tree structures only, not for graphs. In general
Ihave different undirected weighted graphs. So
I need some routing algorithms based on the graph weights, distance calculation between nodes. My first idea was to use
agraph database e.g neo4j, but I have
got a limitation, that the whole system should be designed in Postgres.
Did you can give some ideas to build a graph within Postgres?
Thanks
Phil
