Heterogeneous information systems integration: Organizations and methodologies

In this paper, a methodology for integrating heterogeneous industrial information systems is presented. The methodology is strongly based on the extensive reuse of already-made components and is conceptually divided in three levels, one for each kind of designer that is typically involved in this type of projects. To accomplish a better integration of the activities and tools necessary to develop industrial information systems with the proposed methodology, three appropriate organizational configurations are adopted.
