Model Rules In an Operation

You can model business rules as Business Rule elements in the Business Rules Package, and attach them to the Rule Task elements in a RuleFlow Activity diagram.

Alternatively, in the Business Domain model, if you have operations in the rules processing Class that represent business action, you can define each of those operations as a Rule Task and attach the Business Rules to these operations on the Business Rules diagram or within the Rule Composer.
