Appendix B
Selected Exercises
This appendix contains a set of exercises to allow the readers to check that
they are able to use the concepts, mechanisms and notations from the topic
to develop their own designs and specifications. For this we suggest two kinds
of activity. First, we consider various situations where the RM-ODP concepts
and mechanisms can be used for structuring the specifications of open dis-
tributed systems. After this, there is a small set of additional questions to
check the understanding of some specific ODP concepts.
B.1
Selected Scenarios
Imagine that you are part of a design team that is faced with the following
scenarios. You should consider what form the viewpoint specifications might
take and make suitable proposals for an outline design. You should also exam-
ine the requirements and determine which viewpoints each of the statements
in a scenario have impact on.
The RM-ODP does not prescribe any particular method for building the
individual viewpoint specifications of a system. However, we suggest you
follow the indications given at the end of the chapters that dealt with the
individual viewpoints (chapters 2 to 6), which provided some guidelines on
how to proceed.
B.1.1
Twitter
Suppose that you have done a great job at PhoneMob, and other com-
panies are after you to develop enterprise architecture descriptions for their
businesses. In particular, Twitter
TM
requires documentation of its systems be-
fore embarking on a major IT reorganization.
For this reason, you are asked to write the ODP enterprise and information
viewpoint specifications of Twitter.
