You are developing a CASE tool using UML as its primary notation. You are considering the integration of rationale into the tool. Describe how a developer could attach issues to different model elements. Draw a class diagram of the issue model and its association to model elements.
What will be an ideal response?
This is an open ended question. The main point that should be present in all correct answers is that, ideally,
developers should be able to attach any type of rationale node to any type of modeling element. For example,
developers could attach issues on individual methods, develop proposals which refer to proposed additional methods
and attributes, and discuss arguments which refer to existing model elements. The creation of two abstract classes,
ModelElement and RationaleNode, would make this type of functionality easier to implement (see Figure 12-1).
