SOAda: Service Oriented Architecture with a Decision Aspect

AbstractThe importance of the service orientation and its advantages regard to the information system of the company, confront us to a new challenge. It is primarily a question, of ensuring the decisional aspect of the information system of company by adopting the oriented architecture services like a support architecture. This engineering must ensure on the one hand the flexibility of the information system and on the other hand, avoids the redevelopment of system at the request of the decisions. In the actual position, several obstacles force the installation of the SOA within the company. It is basically a question of the lack of architecture to be implemented to define the services architecture within the information system of the company, which takes into account the decisional aspect. Moreover, there's no existing work which treats this challenge. In this paper, we describe an extended Service-Oriented Architecture - SOAda for supporting a decision aspect. We also present our mete-model MDS (Model decisional of service) to define a new set of concepts necessary for modeling the three sights. Some of them are already known, whereas others are new and are proposed as an element of this work by means of a meta-model
