Ontological Evaluation of the Requirements Model in IS Reengineering: Shifting From a Traditional To a ComponentBased Paradigm,Used
Delivery time: 8-12 business days (International)
The vast majority of present legacy information systems were implemented using the traditional paradigm that consists of modeling techniques used by system analysts such as System Flow Charts and Data Flow Diagrams (DFD) to capture, during the analysis phase, the activities within a system. However, with recent developments, particularly trends towards eCommerce applications, platform independence, reusability of prebuilt components, many organizations are realizing they will need to reengineer their systems into new component based systems that meet these trends given the limitations of legacy systems to adapt to these new technical requirements. There is a high degree of interest and concern in establishing whether or not a full migration to a more portable and scalable componentbased architecture will be able to represent the legacy business requirements in the underlying requirements model of the reengineered information systems. As a result, this study poses the question: Is the resulting componentbased requirements model ontological equivalent to the legacy requirements model when shifting paradigms in the reengineering process?
