Strategies for integrating CASE environments

An experimental information-system environment, called DAIDA (development assistance for integrated database applications), developed as part of the European Community´s ESPRIT program is described. DAIDA goes beyond traditional knowledge-based techniques for CASE by addressing three important dimensions of integration in a process-oriented model: how to handle dependencies among development stages, how to manage the evolving relationship among systems and their technical and social environments, and how to integrate development tasks-from both development in the small, in which the focus is the content of actions and results, and development in the large, which is concerned with object and process management and the collaboration of people involved in developing and using systems. This threefold integration strategy is discussed, along with the DAIDA architecture and a development example. The ConceptBase process information repository, which is used to define the process-oriented integration model, is also discussed.<>
