An Agent Based Encapsulator System: For Integrating and Composing Legacy System Functionalities

Nowadays, Service-Oriented Architectures (SOA) represents the means of Information Technologies (IT) which contribute to the agility of enterprise information systems (IS). Their principle main is to present the applications functionalities as services aligned with the company business. This presentation is promising in the sense that it tends to reduce the costs of integration, to give more importance to the reuse of information system functionalities in different business processes and, of course, to facilitate its adaptation to the unforeseen changes during the life cycle of information system. In this work, we present an approach based on multi-agent systems (MAS) for encapsulating and publishing Legacy system functionalities as web services in the goal to facilitate their integration on a SOA-based Information system. We have on a second part proposed a set of composition templates for composing legacy functionalities.
