A User Centered Design Approach for Transactional Service Adaptation in Context Aware Environment
Today, information systems are radically marked by considerable progress in the areas of software engineering, telecommunications and ubiquitous computing. This has led to the development of new interaction pattern where the service oriented architecture is the de facto pattern. In this article, we are particularly interested in transactional services. We position our approach in the context of a user-centered model driven engineering (MDE) approach in order to move from one perspective where models were contemplative artifacts to a perspective where they become productive artifacts. For this, we first present our approach for managing context-aware transactional services (CATS). Then, we propose a CATS specification and metamodel. The adaptation mechanism is also detailed in this paper.
