Gestion des architectures évolutives dans ArchWare

Work on architecture-centred software development has been undertaken during the past years, leading to the proposition of architecture description languages with high expression power. The concerns that are focused on lately are related to the impact these new approach may have on the software evolution management, namely the possibility of extending the evolution issues to earlier development phases. Several evolution possibilities may be envisaged, depending on whether the evolution was or not foreseen during the design phase, and on whether the evolution takes place during the software execution or not. Existing propositions address some of these possibilities. In this paper we present how the ArchWare languages and environment allow us to cover all the identified evolution
