Understand the Graph View

In Oracle Cloud Infrastructure Process Automation, decisions are created in the graph view. In the graph view, you can create decision requirement diagrams (DRD), in accordance with DMN standards, to visually represent your decisions.

Oracle Cloud Infrastructure Process Automation currently supports one DRD per decision. The following table lists all the available DRD components, which you can use to create your decision.

DRD Component		Description	Icons
Elements	Decision	Denotes a node that determines an output based on its inputs and the logic it contains.
	Input Data	Denotes information used as input by one or more decision elements.
Requirements	Information Requirement	Denotes the flow of information from an input data or a decision element to another decision element.

The graph view is divided into the following areas:

• Toolbar
• Canvas
• Diagram palette

Toolbar

The decision toolbar provides quick access controls to manage the decision canvas.

Toolbar Icon	Name	Description
	Pan Mode	Pan the entire canvas. Note that this is the default mode.
	Undo	Revert the last action.
	Redo	Repeat the last action.
	Maximize view	Open the editor in an expanded view.
	Minimize view	Open the editor in a minimized view.
	Decision service	Open the Services pane.

Canvas

The decision canvas is the central area where you can create a diagram that represents your decision, using the elements in the diagram palette. The zoom controls at the bottom of the canvas allow you to zoom in or fit the canvas in your browser.

Diagram palette

From the diagram palette, drag and drop DRD components onto the canvas to use them in your diagram.

Under Decisions on the palette view all the decision types available for use. You can drag a particular decision type or add an empty decision element and then associate a decision notation to it.
