Software reuse
Objectives
The objectives of this chapter are to introduce software reuse and to
describe approaches to system development based on large-scale
software reuse. When you have read this chapter, you will:
■ understand the benefits and problems of reusing software when
developing new systems;
■ understand the concept of an application framework as a set of
reusable objects and how frameworks can be used in application
development;
■ have been introduced to software product lines, which are made up
of a common core architecture and reusable components that are
configured for each version of the product;
■ have learned how systems can be developed by configuring and
composing off-the-shelf application software systems.
