Abstract : Application development by composition of dynamic and heterogeneous services, that is to say, implemented according to different technologies, is the main subject of this thesis. We believe, actually, that service-oriented approach brings considerable changes in software computing and can bring significant benefits in terms of cost reduction, quality improvement and compression of time-to-market. The service-based technologies have already penetrated in many industries sections and answered certain expectations they aroused. Application development by composing heterogeneous services is still very complex for several reasons. Firstly, the various existing technologies employ very different mechanisms for declaration, research and liaison. The services themselves are described following structures often different. Therefore, development and technical knowledge are necessary to correctly combine services using different technological bases. On the other hand, dynamism management is complex. The principle of the service-oriented approach is to allow late service binding and, in some cases, the change of bindings according to context evolution. This requires very precise synchronization algorithms and is difficult to develop and test. We are well aware that in many cases, the benefits of service-oriented approach are not fully achieved, lacking of appropriate dynamism management. Finally, services are essentially described using a logical syntax. Therefore, we cannot guarantee, in a general case, the compatibility of several services or, more simply, the correctness of their global behavior. This is even more difficult when services have complex interactions, not restricted to a single call to obtain information. In this thesis, we bring a domain-specific dimension into service composition. The domain definition allows restricting the possible compositions of services, both at technical and semantic level. Thus we have found great complementarities between software product lines approaches and service-oriented approaches. Dynamism is a natural characteristic of service-based technologies, that is to say, the ability to bind services as late as possible utile runtime. Software product-lines, in turn, define approaches for planned reuse. Specifically, this thesis provides a three-phase approach for development of service composition with tool support, namely: the definition of a domain in the form of services and reference architectures, the definition of application in the form of service-based architectures and the execution of autonomic applications following application architecture. This thesis is validated in a collaborative project in the home healthcare domain.
