Different process client instances are connected so that they can interact. The same connection mechanism is used to integrate process modules into the process client.
Connections are represented by nodes of type Connection. The connections are held in a Connections folder. For each connection, a group (folder) is automatically created, known as the "connection group". This acts as an inbox for tasks received through the connection and is also used to identify the connection.
Workers and groups keep track of the connections that they need, giving each connection a reference that reflects the role that the connected party takes in the process. Worker and groups use and process connections in different ways.
