问题 I am exploring JanusGraph DBs and require visual editing, like MySQL workbench. I found some visual editors for Neo4j. Are there any visual editors for JanusGraph as well? or can those tools be used with JanusGraph? 回答1: Per JanusGraph's README: To visualize graphs stored in JanusGraph, you can use any of the following tools: Cytoscape Gephi plugin for Apache TinkerPop Graphexp KeyLines by Cambridge Intelligence Linkurious Of these, at least Cytoscape and Graphexp also support visual graph

My question is I have one graph with lot of nodes representing stops of buses. How should I include bus information like which buses available between nodes. I am thinking of creating a buses relationship between nodes that will have info of all the buses between two nodes and a relationship property marking distance between two stops. buses[500A,182A],distance:500m buses[121B,542W,222A,111Z],distance:400m Like A------------------------------------------------------->B----------------------------------------------------------->C So how I will find out the bus or busses( If no direct path is

Comparison of Relational Databases and Graph Databases

由 百般思念 提交于 2019-11-27 10:29:07
Can someone explain to me the advantages and disadvantages for a relation database such as MySQL compared to a graph database such as Neo4j? In SQL you have multiple tables with various ids linking them. Then you have to join to connect the tables. From the perspective of a newbie why would you design the database to require a join rather than having the connections explicit as edges from the start as with a graph database. Conceptually it would make no sense to a newbie. Presumably there is a very technical but non-conceptual reason for this? There actually is conceptual reasoning behind both

I've been designing an application, based on .NET/Mono framework, which should make an heavy use of the shortest-path in a graph theories and I would like to use a native solution to traverse the nodes of the graph, instead of implementing surrogate solutions which would be hardly maintainable and would

问题 I'm currently working on a project where I use natural language processing to extract emotions from text to correlate them with contextual information. Definition of contextual information: Every information that is relevant to describe an entity's situation in time an space. Description of the data structure I'm looking for: There is a arbitrary number of entities (an entity can either be a person or a group for example (twitter hash tags)) of which I want to track contextual information and

What are the use cases of Graph-based Databases (http://neo4j.org/)? [closed]

I have used Relational DB's a lot and decided to venture out on other types available. This particular product looks good and promising: http://neo4j.org/ Has anyone used graph-based databases? What are the pros and cons from a usability prespective? Have you used these in a production environment? What was the requirement that prompted you to use them? I used a graph database in a previous job. We weren't using neo4j, it was an in-house thing built on top of Berkeley DB, but it was similar. It was used in production (it still is). The reason we used a graph database was that the data being

GraphX - Retrieving all nodes from a path

由 痴心易碎 提交于 2019-11-26 22:10:34
问题 In GraphX, is there a way to retrieve all the nodes and edges that are on a path that are of a certain length? More specifically, I would like to get all the 10-step paths from A to B. For each path, I would like to get the list of nodes and edges. Thanks. 回答1: Disclaimer : This is only intended to show GraphFrames path filtering capabilities. Well, theoretically speaking it is possible. You can use GraphFrames patterns to find paths. Lets assume your data looks as follows: import org
