Association in DMN (Decision Model and Notation) refers to the relationship between different elements of a decision model, where one element is associated or linked to another element. Association can be used to represent various types of relationships, such as dependency, influence, or dependency.
For example, in a decision model where a decision is dependent on certain data inputs, the association might be illustrated through a line connecting the decision to the data input. The line would represent the association between the decision and the data input, since the decision is dependent on the input.
