Relational Diagram

A software application that I was documenting had an adjuster package that would adjust calculated values. The adjuster package has sets, rules, and qualifiers. I needed a way to depict the relationship between these three components of the adjuster package in order for users to grasp how to configure the adjusters. For instance, a set may have more than one rule but a rule can only have one qualifier. Another insight communicated in the diagram is that qualifiers do not need to be associated with a rule because a qualifier may have expired or is planned for the future.
