Querying Heterogeneous Engineering Data

In a distributed engineering environment data are represented in many different ways by different systems. The existing commercial DBMS do not support efficient representation and appropriate query language for data formats used in Computer Aided Engineering (CAE) systems. Methods and tools are therefore needed to make it easy to incorporate new kinds of data in DBMS in a uniform way. The main goal of this project is to investigate what database system extensions are needed in order to efficiently represent and query CAE data from different sources and in different formats, e.g. STEP/ Part 21 and XML.

Status

As part of this project we implemented STAmos that is an Amos II wrapper for engineering data in STEP/Part 21 data format. It provides for the following:

Cooperation

This project was part of IEIS , Integrated Engineering Information Systems research program in cooperation with Volvo Aero Corp. and Luleå University of Technology, Department of Mechanical Engineering, Division of Computer Aided Design.
STAmos was used in the research of PhD students from Luleå University of Technology.
