Object-oriented approach to software development, a walk through a number of topics

A number of important software development topics in which the object-oriented approach plays a central role and has caused a significant step forward are examined. An attempt is made to describe these topics in the form of dualities and contrasts. The aim is to present a view of software development which is different from the traditional one, in which the development process has been partitioned into analysis, design, and implementation steps of the life cycle. The authors' viewpoint is based on a vertical partitioning rather than a horizontal one. The list of dualities and contrasts treated in this article contains: waterfall model implies/implied by fountain model, formalism implies/implied by method, functional implies/implied by object-oriented, solution domain implies/implied by problem domain, specification implies/implied by implementation, formal implies/implied by nonformal, declarative implies/implied by procedural, completeness implies/implied by approximation, extension implies/implied by restriction, generalization implies/implied by specialization, refinement implies/implied by coarsening, and composition implies/implied by decomposition.<
