Abstract
An engineering design history is a step-by-step account of the events and the states through which a design artifact evolved. Database technology has not yet provided adequate mechanisms for capturing and reusing design history information. This paper presents an infrastructure for computer-aided archiving and interrogation of engineering design histories. This framework combines research from software engineering, data engineering, and knowledge engineering to develop an environment for the capture and reuse of design histories. A Design Process Representation Language (DRL), is combined with ‘enhanced’ step models to capture design steps and design parameters. This high-level representation is translated into Data Definition Language (DDL) for operations on an object-oriented database. Advances in database technology that are required to fully support intelligent design history systems are discussed.
