OO oversold: Those objects of obscure desire

The principles of object-orientation have been widely used in the area of programming for some time. Their application to the design and specification of software has proved beneficial in a number of ways. In recent years there have been numerous attempts to exploit the same principles in high level design and the analysis of systems requirements. In many cases this has been achieved by extending the principles of object-oriented programming to the earlier phases of analysis and design without recognition that activities and objectives in the different domains may be dissimilar. This paper demonstrates that the endeavour to extend the principles of object-orientation into an all-encompassing method is ill-considered, and that an expansive view of methods integration is more likely to prove conducive in harnessing the strengths of object-orientation to alternative approaches to systems development.

Object-oriented ecosystem modelling

Object-oriented programming (OOP) provides an intuitively natural way to approach ecosystem modelling. The basic concepts of OOP are similar to those underlying the biological sciences, and the techniques used for dealing with the internal structure of objects are appropriate for resolving the problems of hierarchical structure that arise in ecological and other types to complex systems. Even the structure of OOP ecosystem models has a strong resemblance to the structure of the systems being modelled. The relevant principles of OOP are discussed in an ecological context, and the application of OOP to ecosystem modelling is illustrated with several object-oriented models and code segments to show how OOP can simplify model development and modification.

Issues in the design of a parallel object-oriented language

Abstract This paper discusses the considerations that have played a role in the design of the language POOL2. This language integrates the structuring techniques of object-oriented programming with mechanisms for expressing parallelism. We introduce the basic principles of object-oriented programming and its significance for program development methodologies. Several approaches for integrating objects and parallelism are compared and arguments for the choices made in POOL2 are presented. We also explain why inheritance is not yet included in POOL2. A brief overview of the research in formal aspects of POOL is given. Finally we indicate some directions for future developments.
