Abstract

The legacy information systems often implement manual data updates for information obtained from external systems. The manual updates are cumbersome, error prone, and expensive. The legacy systems miss interfaces to external systems that could be used for automatic updates of system data. Moreover, the legacy systems also lack extensions to supplier or customer systems that are essential for creating supply chain relationships. This paper explores the data oriented and process oriented models of legacy systems, and discusses the details of systems development and evolution models mainly aiming at an ongoing reengineering of legacy systems. This paper proposes simple strategies for creating interfaces to external systems for automatic updates of data, and for adapting to the process evolution that requires a legacy information system to extend its communications with external systems that could help in creating successful supply chain relationships. These strategies can reshape a legacy system to be reengineered into a new enterprise information system whether the legacy system is of a data oriented model, or of a process oriented model.
