Conceptual Modeling in the eXtreme

Conceptual Modeling-based methods and their corresponding CASE tools have traditionally had one main weak point: the use of different notations for the problem space system view (centered on the what the system is) and the solution space view (centered on the how it is to be represented). The real value of Conceptual Modeling, from a pragmatic perspective, is lost due to these different notations and the complex and often ambiguous paths required to go from one view to another. To overcome this problem, a Conceptual Schema should be a precise representation of the user requirements and should also be executable. This means that the programming tasks are really done at a higher level of abstraction, using Conceptual Modeling constructs. In this paper, we present a Conceptual Modeling in the Extreme approach for automatic software production this approach focuses the developer's efforts in the Requirements and Conceptual Modeling phases in an extreme way. This approach together with a Conceptual Model Compiler strategy produces a fully executable application. (C) 2002 Elsevier Science B.V. All rights reserved.
