Database support for concurrent digital mock-up

Abstract

This paper presents new techniques to extend digital mock-up applications by state-of-the-art database functionality for concurrent engineering. We propose a database architecture for the efficient management of spatial, structural, and thematic engineering data. This includes methods for representing and indexing CAD files as well as multi-step query processing. Evaluations of the database system show that the proposed query processor performs collision queries on a 2.5 gigabyte CAD database within seconds, plus the time required by the digital mock-up tool
