Past and future models of CASE integration
Alan W. Brown, Peter H. Feiler, Kurt Wallnau · 2003
Two key approaches to building integrated software development environments are analyzed. They are the integrated project support environments (IPSE) approach, and the computer-aided software engineering (CASE) coalitions approach. The strengths and limitations of these approaches are discussed, leading to the definition of a model of integration that separates process, end-user service, and mechanism concepts, relating them in a three-schema view of integration similar to the ANSI/SPARC database model. This model provides the basis for a deeper understanding of integration issues within a SDE, and points the way toward an architecture for future SDEs that combines the benefits of the IPSE and CASE coalition approaches.>
