Dependencies are displayed in Luna Modeler using specific lines between objects.
These can be created automatically using the Infer dependencies feature, or manually.
How to detect dependencies in your data model
Automatic dependency detection is based on scanning the code of objects such as views, functions, stored procedures, etc. Once the name of another object is found in the code, a dependency line is created.
To start detection, click the Advanced button on the main toolbar and select Infer dependencies
or right-click on the diagram canvas and select Advanced -> Infer dependencies from the context menu.
Automatically created dependency lines will be displayed in the diagram.
How to create a dependency line manually
Dependency lines can be added to the diagram manually to any object. This can be ENUM in models for PostgreSQL, etc. It is also possible to create a dependency line to indicate a specific dependency between tables or to create a dependency to text or a note.
To add a dependency line, simply create a new line and change the line style from classic to dependency in the properties.

How to show or hide dependency lines
The number of dependencies can be quite extensive, and a diagram showing both relationships and dependencies can become less clear. Therefore, you have the option to show or hide all dependency lines at once.
To show or hide dependency lines, simply toggle the option in the Display menu. Similarly, you can choose whether to show dependency captions and whether to animate relationship lines and dependencies.
Deleting all dependency lines
If you do not want to have dependencies in your model, you can easily delete them. Right-click on the diagram and select Advanced -> Delete dependencies. This operation will delete all dependency lines, both automatically detected and manually created.
Working with the Dependencies layout
If you are more interested in dependencies, you can use the Dependencies layout, which arranges objects in the diagram so that greater weight is placed on dependencies than on relationships.
Dependencies in HTML reports
Information about dependencies is also displayed in generated HTML reports, both in a separate section and in the details of a table or other object.
