Towards a model of adaptation and interfacing based on a middleware layer SOA for interoperability of several different information systems

With the revolutionary development of information technologies and information systems, companies are obliged to face this change by adapting their business processes and using advanced technologies. IT have become the backbone of any organization, they are essential and indispensable for its structural and organizational management. Companies need to exchange, provide information on their information systems and especially collaborate. But this interconnection is unfortunately facing challenges especially when it comes to real-time exchange or merger of all or part of the information system. Interoperability between information systems has become an obligation for all businesses, but the information systems are designed and developed in various ways. MDA is the right solution for interoperability; they offer several improvements in the development of complex systems independent of the technical platform. In addition, the SOA services oriented architecture is a technology that allows the encapsulation of the complexities of all the components of the information services and this system with the aim of satisfying the need for alignment of information system with the corporate strategy and business process automation. In this paper, we propose a model, based on a middleware layer composed of services as SOA, to interoperate several information systems (IS).
