EDAPLEX an Object-Oriented Extension of DAPLEX for Engineering Applications,igate in this paper is computer geometry. In this paper we first provide a brief introduction to geometric modelling from a database perspective. The functional data model with its database language DAPLEX is analyzed as a candidate for supporting computer geometry applications. It is argued that th

Using an NF2 Data Base System for Modeling of CIM Data,led non-standard applications, of which we consider the CAD/CAM applications in the present work. We first describe the basic object classes of a particular CAD/CAM application area, a manufacturing cell. A top down design methodology is presented which supports the hierarchical modeling of a databa

,Datenmodelle für VLSI-Entwurfsdatenbanken,D because of their limited data models which are tailored to simple object structures. Thus, the complexity of CAD objects can only be represented indirectly. Modelling of VLSI-CAD data requires at least five basic structuring mechanisms: complexity, composition, versioning, representations and abst

,Konzepte zur Suche geometrisch ähnlicher Bauteile,Form der Anfrage ist die Suche nach ähnlichen Teilen - im Maschinenbau auch als Wiederholteilsuche bezeichnet-, um den Aufwand für die Konstruktion und die Produktionsplanung wesentlich zu verringern. In allen bereits verfügbaren Systemen werden Objekte durch einmalig festzulegende Attribute beschri
