Edges, Identifiers, Handles

A graph data model always consists of at least two collections: the relations between the nodes in the graphs are stored in an “edges collection”, the nodes in the graph are stored in documents in regular collections.

Example:

• the “normal” collection stores all the properties about the reception, e.g. that 20 people are working there and the room number etc
• _to is the document handle of the linked vertex (outgoing relation)

To change edge endpoints you can simply update the and attributes like any other document attribute.
