The Geometrie Data Model DB-GEOMOD in Engineering Data Base Environment

This paper presents a new data model (DB-GEOMOD) to manage the geometrical data and the non-geometrical data in engineering data base environment.Representing the geometrical data in NET/RELATION hybrid model, we can manage the geometrical and non-geometrical data in the same way. In this case, the paper presents an idea to integrate the geometrical and nongeometrical data in data base enviroument.
