Contribution to Interoperability of Executive Information Systems focusing on data storage system
Résumé
Nowadays, performance improvement in order to reach the economic, technical and social objectives has become essential for all enterprises whose want to stay competitive. For this reason, enterprises should set up an executive information system which will give them their performance's level at every moment through different performance indicators. The developement of those systems is long and difficult and different ineroperability problems can occur especially during the design of the data storage system. Those interoperability problems disturb the system and the agregation of the different performance indicators. This article aims in a first part to propose a framework for the design and implementation of the data storage system. In a second, we analyse the different possible architecture and make their comparison.
