FIGURE A.16: Correspondences from computational to engineering objects.
Another example of this kind of correspondence is the set of relationships
between engineering and computational objects. This is shown in figure A.16.
Note that object names do not always coincide.
The second kind of correspondence happens when the related objects do
not represent the same entity but there is still a relationship between them.
A typical example is an enterprise policy that affects several information or
computational elements. In this case, the purpose is twofold. Firstly, the
correspondences specify how the policy constrains the related elements and,
secondly, the correspondences provide the traceability mechanisms required
to identify the elements that are affected by the policy and, conversely, the
policies that affect an individual viewpoint element.
This kind of correspondence is also used to specify the choice of technology
required to implement and deploy the engineering nodes and channels. This
is illustrated in figures A.17 and A.18, where the correspondences represent
