108 Model Driven Systems Development with Rational Products
The integration of concerns is accomplished by sharing interfaces with the logical
entities. Figure 6-16 shows how operation signatures can be shared between the
logical entities and the distribution entities. This ensures that the operations
shared between them are the same operations. These interfaces can be put in
the Joint Realization package (see Figure 6-13 on page 106).

Automation
Several parts of the model structure are manually created at this time. The
Building Blocks template is an example of a pattern used multiple times to keep
consistency in naming, as well as look and feel. A current effort is going on to
discover such patterns and
automate their creation programmatically within the
MDSD plug-in. This might change some of the structure described above, but
allow for better consistency and traceability.
