Service-driven information systems evolution: Handling integrity constraints consistency

Abstract

Changes and extensions of enterprise information systems (IS) often engender their fragmentation and redundancy. In order to overcome these problems, service-driven IS development is considered as a potential solution to support IS evolution when guaranteeing its integrity and consistency. In this work we consider the integration of new information system services (ISS) into a legacy IS and, in particular, how the consistency of integrity constraints (IC) governing the IS and the new ISS has to be handled in order to guarantee their validation. Five IC handling strategies are proposed in the form of method chunks and the impact of their application is measured with four service evolution indicators. © 2009 IFIP International Federation for Information Processing.
