Abstract

This paper proposes a comprehensive framework for the analysis of sets of data, processes, and applications of legacy information systems in view of restructuring interventions, according to different perspectives. A "data asset structure perspective" supports the information system analysis in terms of semantic correspondences between data assets shared by different organization units and applications of the system. An "operational structure perspective" supports the information system analysis in terms of the semantic correspondences between processes, with respect to the similarity of the involved data and operations. Finally, an "organizational structure perspective" supports the information system analysis in terms of the organization unit cohesion and coupling properties with respect to the exchanged information flows. The perspectives are discussed with reference to the analysis of italian Public Administration information systems.
