Intégration de la modélisation comportementale dans la conception par points de vue

Abstract : View-based modeling is the main subject of this thesis. It is a variant of the object oriented modeling approach for the analysis and design of complex systems, focusing on the actors that use the system and decomposing the specification according to their needs. With this prospect, our team developed a UML profile named VUML (View based UML), which allows the elaboration of a unique and sharable model accessible according to the view of each of the system's actors. However the achieved work on the VUML profile does not tackle the behavior aspects of the modeling process. The VUML approach address the structural aspects related to the composition of views and to the sharing of data without dealing with the way these views will react, or how to be able to synchronize them in order to obtain the behavior of multiple-view objects (instances of a multi-view class). The achieved work in this thesis aims to fill this gap by providing new mechanism to the VUML profile that allows expressing the behavioral needs of a system. We will focus on describing the individual behavior of multi-view objects by state-machines that require adjustments of UML modeling concepts. To achieve this objective we introduced the concept of event probes, which allow to specify implicit communication between the view-objects via event observation. This allows decoupling the view specifications that are a priori strongly interconnected, and therefore allows them to be designed separately, in agreement with the VUML method recommendations, and then to be integrated without the need of making modifications. We first define the concept of event monitoring and identified the different types of probes and the appropriate parameters that characterize them. We also define a set of concepts that can extend and manipulate probes. Then we propose a UML-compatible representation of the introduced concepts in form of a profile named VxUML (extension of VUML). In addition to defining the profile elements (stereotypes, tagged value, predefined library classes), we have developed rules for proper formation of the static semantics using OCL to reduce ambiguity in the specification of such concepts. Afterwards, to demonstrate the usefulness of the concepts introduced, we developed a case study through which we sought to provide a full view-based model, addressing both structural and behavioral aspects. At the end, to concretely validate our approach in a model driven engineering setting, we developed a code generator that takes as input a specification developed in VxUML profile. This generator uses the techniques of model transformation related to the code generation, including transformation of platform independent models (PIM) to platform specific models (PSM), and transformation of PSMs to code; the current target language is Java. Finally, another contribution of this thesis is a process associated with VxUML. It is an approach that complements the approach associated with VUML (which deal only with structural aspects) to be able to use in methodical manner the new mechanisms dedicated to behavioral treatment. Now, the VxUML development process offers a complete view based modeling, that is, dealing with both structural and behavioral aspects. Keywords: View based modeling, VUML profile, VxUML profile, event observation, multi-view states machine, behavior composition.
