In any DMN model, you start by creating a Decision Requirements Diagram (DRD). A DRD is the visual representation of a DMN model, known as a Decision Requirements Graph (DRG). A DRG can consist of one or more DRDs or diagrams.
You model Decisions in diagrams using a standard palette of components.
You can have multiple decisions in the one diagram or spread them over multiple diagrams to avoid complex decision models that are difficult to read.
Before you start modeling your decisions, get to know how diagrams work, how to format them, configure decision definitions, view decision structure and reports, and download decision models and images.
Before you start, get to know the DMN Design page. The Design page is where you model and edit decisions.
The header contains these elements:
Cardanit logo: click to go to the Home page.
Menu: Go to My Files, rename the project, and go to the Simulations page which lists the simulations that have been run.
A tab menu that gives you access to the Design, Logic and Report pages.
Access to version history.
See who the project is shared with and share the project with others.
View your profile.
Access the help section.
The tools in the toolbar are for editing and downloading the DMN model and diagram screenshots.
The Element Palette shows the components you can use in the diagram.
Use
The diagram tab bar at the bottom of the screen is where you manage diagrams.
A diagram is where you create, map and edit your decisions.
In the Panel gives you access to the decision structure, decision definitions and component attributes and the style section where you can customize the appearance of your diagram.
Zoom in and zoom out or reset visualization, and access the mini-map.
You can add, rename and delete diagrams and move diagram tabs in the sequence you prefer.
You perform these actions in the diagram tab menu at the bottom of the screen.
To add a diagram:
In the diagram tab bar, click
This places the diagram at the end:
You can also choose where to add a diagram: at the start, at the end, right or left.
Click
In the dialog box that opens, give a name to the diagram, then click Ok.
If you delete a diagram it can’t be restored.
You can move diagram tabs in the sequence you prefer: left,right, to the start or end.
Click
Or select the tab and drag and drop into position.
You can customize the appearance of components and labels to make your diagram clearer and easier to read.
To customize the style of a component in your diagram:
Select the component, then click Style in the Panel Menu.
If you don’t like your style changes, click Reset to return to the default style.
To select multiple components of the same type — for example, all the Decisions in the diagram:
Press Shift, then select all the components you want to format.
In the Style panel that opens, depending on the type of component you want to change, you have these formatting options:
Format the color of components.
Fill: color the inside of a component.
Stroke: color the outline of a component.
Format label text and paragraph styles.
Text: change the font type, font size, color and text style, align text and position.
Format the appearance of Knowledge, Information and Authority Requirements and Associations.
Color: Color the line.
Style: Choose between straight and elbow.
Radius: Change the curve radius.
Definitions is the root container for all the components of a DMN decision model. Cardanit automatically detects and lists all the Definitions in the DMN model.
You add, edit and remove Definitions in the Definitions panel. Alternatively, you can configure Definitions using shortcuts in the Attributes panel of certain Elements.
The Definitions panel is divided into tabs.
This action is applicable to all Definitions except for Attributes.
Open the tab of the Definition you want to add, then click Add.
Select the Definition and complete the Definition fields.
This action is applicable to all Definitions except for Attributes.
Open the tab of the Definition you want to remove.
Select the Definition, then click Remove.
The Structure panel displays all the aspects of a diagram in alphabetical order in a real time, synchronized tree structure.
When you add something to a diagram, the Structure panel updates in real time to reflect what you see in the diagram.
When you select an element in the diagram, the element is highlighted in the tree. Once you’ve selected an element you can open the Attributes panel to define its attributes.
Use Search to explore the structure and find a specific item in the diagram.
Cardanit generates a comprehensive decision report that enables you to analyze processes offline in a familiar format.
The report is generated in real time and contains all the diagrams in the decision. It includes everything from Attributes and Definitions to diagram graphics and images.
Preview and download the process report on the Report page. You can download the decision report in Microsoft Word DOCX and Adobe PDF format.
You can download diagrams as a DMN 1.3 XML file to back up your work or to use with other DMN-compatible software.
You download DMN 1.3 XML files on the Design page.
You can download an image of a single diagram or multiple diagrams as a PDF or PNG file.
You download diagram images on the Design page.
In the Toolbar, click
In the dialog box that opens, select which images to download, the file format and show or hide project information and the watermark, then click Download.
