Abstract:
To face the increasing complexity of software systems and to meet new needs in flexibility, adaptability and maintainability, classical object-oriented technology is not powerful enough. As pointed out by many authors, one must take into account the multiplicity of actors’ viewpoints in complex systems development. Views, subjects, roles and aspects are viewpoint-oriented concepts that permit a flexible adaptation of modelling and use of systems. This article aims to provide software developers with a comparison between view, subject, role and aspect approaches in respect to their principles and impacts on systems development as well as on systems use. After a brief presentation of these approaches, we discuss their similarities and differences by means of criteria positioning them along the software lifecycle.
