Generating code for engineering design systems using software patterns

Abstract

We illustrate here how software engineers developing engineering design systems can introduce patterns into the conceptual modeling techniques that were developed in the database community and integrate them with techniques that are emerging in the object-oriented analysis and engineering design community. The goal is to raise the level of abstraction used to communicate software specifications and to build applications. This will speed the development and improve the quality of engineering design tools. We show by an example how this can be accomplished through an example software pattern from the software engineering discipline (the observer pattern) [12]. We show how patterns can be automatically supported using the general techniques that were developed in the Semantic Objects, Relationships, and Constraints (SORAC) project [20] for the development of tools, for the specification of databases and for building design systems.
