Output Nodes
Every different analytic module will have it's own unique nodes.
Some of these nodes are output nodes - they have inputs but may not have any outputs. They are the destination for your analytic data.
After the data reaches an output node, it's then processed by ARDI.
Final Output Nodes
A final output node is an node that has inputs, but no outputs. This is the end of the line for your node graph, as nothing can come after it.
