Toward the Development of a hybrid model of ontological database for the interoperability of several information systems

The problem which companies want to face is the integration of the applications in an information system (IS) and the interconnection of the system itself with other information systems. The interoperability of IS constitutes, their ability to communicate and to interoperate following a given model using a common language favoring the sharing of information for better performance and profitability. [1] In this article we reminder of the model that we have proposed for the interoperability of IS, it is a model of interconnection having for objective the synchronization of the business process of IS interconnected. This synchronization is based mainly on the transformation of business processes BPMN (Business Process Model Notation) of the different IS in Executable Languages Business Process Execution Language (BPEL) thanks to a language ATL (ATLAS Transformation Language) then bring together all the BPEL in a single global BPEL to basis of the rules of adaptation and an ontological database. Then and using the reverse engineering, to make an update, well adapted, Process BPMN trades of different IS. The key point of this architecture is the use of the ontological database. We present in this article a new hybrid model of ontological database based on two approaches of schema of ontological storage different that we were able to create from the result of analysis of a comparative study of database systems to ontological basis (BDBO). This analysis has helped us to adopt a hybrid model of BDBO who owns his own architecture and its storage model. This hybrid model that we are going to adopt for the implementation of the interoperability model of several information systems.
