In the book, a notation is suggested for use along with the analysis approach as it was recognised that an analytical method needs a supporting notation for it to be practical. My first thought was for component diagramsbut I have always viewed components as principally an implementation concern rather than part of the problem domain.
Whilst the component definitions will usually coincide with natural divisions in the problem domain, it seems incorrect to be talking about interfaces etc. I also considered package diagrams but this also seems inappropriate. I use package diagrams as part of deciding how the components are to be grouped in terms of the source code repositories; this is closely related to my deployment strategy as each package will be intended for deployment to a particular server.
There’s no specific granularity for yourdln block – it could be another system, a subsystem, component, class, and so on. If you want to stay within UML, I wouldn’t dismiss package diagrams so quickly. What you are describing could be viewed, from one perspective, as a “package”.
CPSC Coad and Yourdon’s Method for Object-Oriented Design
Scott Ambler’s discussion of package diagrams in Agile Modeling supports this perspective, as well. Personally, I don’t have a problem mixing notations. A viewpoint shows the design from the perspective of a particular stakeholder, using one or more views. Views can be in any form, but are usually graphical and sometimes tabular with supporting text.
