Symphony: un modèle conceptuel de composants métier

Fifteen years after the object promising beginning, object oriented methods are not really used in the companies. Several reasons can be quoted, in particular the fact that components reuse during the analysis and design stages of application development remains difficult. The work undertaken around the Symphony method adresses this problem. Its aims are to give a user centric vision, to optimize the reuse of components during the analysis and design stages and to facilitate the applications evolutions. Symphony is a component based method which drawn out of Umanis experiences. An application is seen as an assembly of independent and inter-connected components as well at conceptual level as at the software level. This article stresses the components conceptual model and their relations.
