A Flexible Object-Oriented Software Architecture 123
Moreover, the transition from structured (C) to object-oriented (C++)
software development on the specific target platform has proven feasible in
terms of both code size and run-time performance, although definite comparisons
to the previous, C-based implementation will only be possible once
the modeled tracker application’s functional scope has reached that of the
previous implementation.
Discussions have furthermore indicated significant enhancements in terms
of documentation and comprehensibility achieved through modeling the
software in UML, suggesting that secondary benefits, such as improved maintainability
and adaptability of the tracker application by customers, have in
fact been achieved as well.
Of course, the precise degree to which a UML-based middleware framework
architecture and a product-line-based application development approach
help further maintainability and extensibility will only become evident once
the architecture is being employed in practice – and so will the overall quality
and flexibility of the design in comparison to the previous, conventional
approach.
NOTE

Due to the limited scope of this chapter, the included diagrams offer only a superficial glance
at selected aspects of the model. A much more detailed discussion of the project is provided in
German in the author’s diploma thesis [4].
