General Graphs
This chapter describes the general-graph module.It allows you to define a graph that is spread across several edge and document collections.This allows you to structure your models in line with your domain and group them logically in collections giving you the power to query them in the same graph queries.There is no need to include the referenced collections within the query, this module will handle it for you.

Three Steps to create a graph
Create a graph
- arangosh> var graph_module = require("@arangodb/general-graph");
- arangosh> var graph = graph_module._create("myGraph");
- arangosh> graph;
Show execution results
Hide execution results
- {[Graph]
- }
Add some vertex collections
- arangosh> graph._addVertexCollection("shop");
- arangosh> graph._addVertexCollection("customer");
- arangosh> graph._addVertexCollection("pet");
- arangosh> graph;
Show execution results
Hide execution results
- {[Graph]
- }
Define relations on the Graph
- arangosh> var rel = graph_module._relation("isCustomer", ["shop"], ["customer"]);
- arangosh> graph._extendEdgeDefinitions(rel);
- arangosh> graph;
Show execution results
Hide execution results
- {[Graph]
- }
