Connecting the Dataflow

Now we shall connect it both to the putty Client object and to the sshd Service object. Start by clicking on the Network objects and their left arrows and then select the Host objects to show them on the canvas.

Then hold down the [Shift] key and drag a connection from the Information Request to Windows 10 workstation.

Since a Dataflow shall not be connected to a Host object but instead to the Client object in the Host object, we need to use the left-bound arrows on the Host objects to display the Client and Service objects as well.

Renaming the Client to putty and connecting the Dataflow Information Request to both the Client and the Service object shall give the following on the canvas.

Then you can hide the Host, Client and Service objects again by selecting them and pressing backspace.

This is a good opportunity to describe Indirect Associations. They are not enabled by default, but if you right click on the canvas, you will see an option to enable them. Doing so, a new kind of connection line is then shown between Information Request and ClientZone and ServerZone; an indirect connection. It is showing that there is a connection between Information Request but not directly to these zones but to something within them.

We also see that holding and keeping the mouse pointer over the indirect connection, presents a label showing (a list of) what associations the indirect association represents.

Hovering the mouse pointer over the indirect connection brings up a label saying that Information Request is connected to Router and the connection type is Communication.
