Konfigurierungskonzepte für DB-basierte technische Entwurfsanwendungen

Zusammenfassung. Schwerpunkte einer Datenbank-Unterstützung von technischen Entwurfsanwendungen sind eine geeignete Ablaufkontrolle sowie ein geeignetes Datenmodell. Letzteres muß Versionen komplexer Objekte verwalten können. Um aus der Gesamtmenge der in einer Datenbank enthaltenen Versionen konsistente Einheiten (Mengen ‚kompatibler’ Versionen) hervorheben zu können, werden geeignete Konfigurierungskonzepte benötigt. Dieses Papier gibt eine Klassifikation verschiedener DB-bezogener Konfigurierungsansätze, bewertet diese und begründet damit die Wahl, die im Rahmen des Objekt- und Versionsdatenmodells OVM hinsichtlich des zu unterstützenden Konfigurierungskonzeptes getroffen wurde. Wir werden argumentieren, daß insbesondere die Flexibilität, die das gewählte Konzept sowohl hinsichtlich der Definition von Konfigurationstypen als auch hinsichtlich des Anlegens von Konfigurationen bietet, zu einer besseren Unterstützung von technischen Entwurfsanwendungen als in bestehenden objekt-orientierten Systemen führt.Abstract. Data model and process control are key issues of database support for technical design applications. The data model has to provide adequate versioning and configuration services. The latter are of major importance for establishing consistent units of versions (sets of ’compatible' versions). This paper classifies and assesses DB-related configuration concepts. This assessment proves that the approach taken by our model OVM (Object and Version Model) is appropriate to flexibly support technical design applications. We will argue that especially the flexibility of the OVM configuration concepts (w. r. t. both, definition of configuration types as well as handling of configurations) leads to a better support as the one provided by current object-oriented systems.
