Zusammenfassung

Im Bereich geographischer Datenbanksysteme liegen aufgrund der Komplexität der Objekte und Anfragen sowie der extrem großen Datenvolumina besondere Anforderungen an die Speicher- und Zugriffsarchitektur in bezug auf eine effiziente Anfragebearbeitung vor. In den letzten Jahren wurden eine Reihe von Konzepten, wie räumliche Indexstrukturen, Approximationen, Objektzerlegung und Mehrphasen-Anfragebearbeitung als einzelne Bausteine vorgeschlagen und analysiert, um die Leistungsfähigkeit von Geo-Datenbanksystemen zu steigern. In dieser Arbeit beschreiben wir eine globale Speicher- und Zugriffsarchitektur, die sich modular aus obigen Bestandteilen zusammensetzt. Um einen mengenorientierten Zugriff großräumiger Bereichsanfragen effizient zu unterstützen, haben wir unsere Geo-Architektur um das neue Konzept einer Szenen-Organisation erweitert. Ein experimenteller Leistungsvergleich zeigt, daß sich durch diese Szenen-Organisation massive Leistungssteigerungen, insbesondere für große Bereichsanfragen erzielen lassen.
