This version is deprecated. Download the new version of ArangoDB

With the 2.2 release we proudly announce that we now offer the feature of multi collection graphs. This allows you to group an arbitrary set of ArangoDB collections into one graph. In order to do this grouping you execute the following steps in arangosh or Foxx: 1. Require the general-graph module and create a graph.

var graph_module = require("org/arangodb/general-graph");
var graph = graph._create("myGraph");

1. Add collections to be used as vertex collections. If the collections are not yet created, ArangoDB will create them for you.

graph._addVertexCollection("person");
graph._addVertexCollection("publication");
graph._addVertexCollection("university");
graph._addVertexCollection("company");

1. Create edge definitions between your vertex collections. These definitions create edge collections and allow you to store edges where source and target vertices come from the collections written in the definition. If you give vertex collections unknown to the graph they will be added to the graph. (more…)

Using ArangoDB as your graph database?

you now have the opportunity to visualize your data graphically, using the “Graphs” tab in the admin interface.
In this post i will explain you how to do this:

Step 1) Configure the Interface
At first you have to configure the interface to display exactly the data you desire.
For the dataset you have two options:

1. Select one vertex and one edge collection directly
2. Select the graph by name created using the graphs api
3. Manage your graphs

Then the interface offers you several advanced options:

1. Decide if the graph is directed (only outbound edges are followed) or undirected (all edges are followed). By default we treat your graphs as undirected
2. Define if you want to start at a random vertex in the graph. By default we will do that.
3. Then you can define which of your attributes should be used as the label on the verticies. By default we will use the _key for this.
4. Now lets bring in some colour. You can either use the same attribute for colouring as for labeling, but you can also use a different one
5. Finally you can define a grouping of new nodes. This is useful to speed up the performance of the interface and to increase the usability. You can define a priority list of attributes here, which is elaborated from top to bottom: All vertices having the first attribute defined are grouped by its value. All other nodes are grouped by the second attribute if present etc.

In the latest version of ArangoDB (1.4) we have introduced a new tab in the Admin Interface: Graphs.

You can use this tab to view and modify your graphs stored in ArangoDB.
In this screencast you will get a short introduction on how to use the new system.
