Hello guys, I am totally newbie in graph databases, I saw several tutorials and I asked couple of days ago for help with cypher query. Then I realized that my data model is not optimal, and I should design a new one by myself for my needs. Right now ...

I am new in neo4j, I created a graph following this steps, based on a data model from GTFS. I would like to find all the shortest indirect routes in the graph (with transfers). Data model of graph database contains 4 entities: Route, Trip, Stop, Stop...

You are right, the design is not great for this model. "OPERATES" is deleted, i just leave it there instead of using WITH p. I make several tests and realised that shortestpath method work with number of hops from A to B. I need to add distance of tr...

For example when you look at this screenshot. Stop (A) = BCT ... Stop (T) = DDR (transfer) ... Stop (B) = NDLS ... It means that if you want get from Stop A to Stop B you have to get out from train at transfer station (T) in this case DDR.

@ganesanmithun323 OK, I understand so this is my db.schema(): For better understanding, the node of Stoptime realizes a sequence of Stops through which train/bus (trip) is going, has attribute arrival (arr.) and departure (dep.) time. As you can see...

Hello, I still struggling to make this query work, I tried to take apart the query and understand to their parts. I realized that this query is not proper because of the method nodes() return list of nodes. But there are different types of nodes (Sto...

Thanks, I did it, also deleted semicolon but now I have a different problem it's such slow, after waiting several minutes I get an error message that There is not enough memory to perform the current task. With compare of my first query on the top wh...
