174 Chapter 6 Architectural design

6.5. Explain why you normally use several architectural patterns when designing the architecture
of a large system. Apart from the information about patterns that I have discussed in this
chapter, what additional information might be useful when designing large systems?

6.6. Suggest an architecture for a system (such as iTunes) that is used to sell and distribute music
on the Internet. What architectural patterns are the basis for this architecture?
6.7. Explain how you would use the reference model of CASE environments (available on the
book’s web pages) to compare the IDEs offered by different vendors of a programming
language such as Java.
6.8. Using the generic model of a language processing system presented here, design the
architecture of a system that accepts natural language commands and translates these into
database queries in a language such as SQL.
6.9. Using the basic model of an information system, as presented in Figure 6.16, suggest the
components that might be part of an information system that allows users to view information
about flights arriving and departing from a particular airport.
6.10. Should there be a separate profession of ‘software architect’ whose role is to work
independently with a customer to design the software system architecture? A separate
software company would then implement the system. What might be the difficulties of
establishing such a profession?
